Theory of the P wave detection

The algorithm first finds the  the possible positive and negative wave peaks
based on zero transition searching, then validates them with comparing
to reference P waves.

The P wave detection needs high amplitude resolution. This value is better,
than 0.6 uV / bit in the Cardiospy system.  With this resolution and
the effective filter system which uses wavelet transformation,
the Cardiospy system is able to detect P waves less than 50 uV of amplitude.

 

Validation of the P wave detector

The validation is carried out on 10 pcs 12 channel and 10 pcs 3 channel ECG
reference records. The reference records include the P wave  annotation.  12
of the 20 records are taken from the MitBih database, 8 records are
taken from the Labtech database (30000 – 30007).

Abstract

Background

Despite increased interest in non-invasive arterial pressure monitoring, the majority of commercially available technologies have failed to satisfy the limits established for the validation of automatic arterial pressure monitoring by the Association for the Advancement of Medical Instrumentation (AAMI). According to the ANSI/AAMI/ISO 81060–2:2013 standards, the group-average accuracy and precision are defined as acceptable if bias is not greater than 5 mmHg and standard deviation is not greater than 8 mmHg. In this study, these standards are used to evaluate the CareTaker® (CT) device, a device measuring continuous non-invasive blood pressure via a pulse contour algorithm called Pulse Decomposition Analysis.

Methods

A convenience sample of 24 patients scheduled for major abdominal surgery were consented to participate in this IRB approved pilot study. Each patient was monitored with a radial arterial catheter and CT using a finger cuff applied to the contralateral thumb. Hemodynamic variables were measured and analyzed from both devices for the first thirty minutes of the surgical procedure including the induction of anesthesia. The mean arterial pressure (MAP), systolic and diastolic blood pressures continuously collected from the arterial catheter and CT were compared. Pearson correlation coefficients were calculated between arterial catheter and CT blood pressure measurements, a Bland-Altman analysis, and polar and 4Q plots were created.

Results

The correlation of systolic, diastolic, and mean arterial pressures were 0.92, 0.86, 0.91, respectively (p<0.0001 for all the comparisons). The Bland-Altman comparison yielded a bias (as measured by overall mean difference) of −0.57, −2.52, 1.01 mmHg for systolic, diastolic, and mean arterial pressures, respectively with a standard deviation of 7.34, 6.47, 5.33 mmHg for systolic, diastolic, and mean arterial pressures, respectively (p<0.001 for all comparisons). The polar plot indicates little bias between the two methods (90%/95% CI at 31.5°/52°, respectively, overall bias=1.5°) with only a small percentage of points outside these lines. The 4Q plot indicates good concordance and no bias between the methods.

Conclusions

In this study, blood pressure measured using the non-invasive CT device was shown to correlate well with the arterial catheter measurements. Larger studies are needed to confirm these results in more varied settings. Most patients exhibited very good agreement between methods. Results were well within the limits established for the validation of automatic arterial pressure monitoring by the AAMI.

and central pressure. Therefore, basing treatment decisions on central, rather than brachial pressure, is likely to have important implications

for the future diagnosis and management of hypertension. Such a paradigm shift will, however, require further, direct evidence that selectively

targeting central pressure, brings added benefit, over and above that already provided by brachial artery pressure.

Central pressure Blood pressure Anti-hypertensive treatment Cardiovascular risk

Introduction

The brachial cuff sphygmomanometer was introduced into medical

practice well over 100 years ago, enabling the routine, non-invasive,

measurement of arterial blood pressure. Life insurance companies

were among the first to capitalize on the information provided by

cuff sphygmomanometry, by observing that blood pressure in

largely asymptomatic individuals relates to future cardiovascular

riskobservations that are nowsupported by a wealth of epidemiological

data.1 The most recent Global Burden of Disease report2

identified hypertension as the leading cause of death and disability

worldwide. Moreover, data from over 50 years of randomized controlled

trials clearly demonstrate that lowering brachial pressure,

in hypertensive individuals, substantially reduces cardiovascular

events.1,3 For these reasons, measurement of brachial blood pressure

has become embedded in routine clinical assessment throughout the

developed world, and is one of the most widely accepted surrogate

measures for regulatory bodies.

The major driving force for the continued use of brachial blood

pressure has been its ease of measurement, and the wide variety of

devices available for clinical use. However, we have known for over

half a century that brachial pressure is a poor surrogate for aortic

pressure, which is invariably lower than corresponding brachial

values. Recent evidence suggests that central pressure is also more

strongly related to future cardiovascular events4 7 than brachial

pressure, and responds differently to certain drugs.8,9 Appreciating

this provides an ideal framework for understanding the much publicized

inferiority of atenolol and some other beta-blockers,10 compared

with other drug classes, in the management of essential

hypertension. Although central pressure can now be assessed noninvasively

with the same ease as brachial pressure, clinicians are unlikely

to discard the brachial cuff sphygmomanometer without

robust evidence that cardiovascular risk stratification, and monitoring

response to therapy, are better when based on central rather

than peripheral pressure. Central pressure assessment and accuracy

will also have to be standardized, as it has been for brachial pressure

assessment with oscillometric devices. This review will discuss our

current understanding about central pressure and the evidence

required to bring blood pressure measurement, and cardiovascular

risk assessment into the modern era.

Physiological concepts

Arterial pressure varies continuously over the cardiac cycle, but in

clinical practice only systolic and diastolic pressures are routinely

reported. These are invariably measured in the brachial artery

using cuff sphygmomanometrya practice that has changed little

over the last century. However, the shape of the pressure waveform

Pressure measured with a cuff and sphygmomanometer in the brachial artery is accepted as an important predictor of future cardiovascular risk.However, systolic pressure varies throughout the arterial tree, such that aortic (central) systolic pressure is actually lower than corresponding brachial values, although this difference is highly variable between individuals. Emerging evidence now suggests that central pressure is better related to future cardiovascular events than is brachial pressure. Moreover, anti-hypertensive drugs can exert differential effects on brachial and central pressure. Therefore, basing treatment decisions on central, rather than brachial pressure, is likely to have important implications for the future diagnosis and management of hypertension. Such a paradigm shift will, however, require further, direct evidence that selectively targeting central pressure, brings added benefit, over and above that already provided by brachial artery pressure.As discussed earlier, a full synthesis of the available evidence concerning

central pressure and the risk of future cardiovascular events is now required. However, it will also be necessary to determine the clinical relevance of differences between brachial and central pressure

for the individual patient, especially given the relatively high correlation between the two. Emerging data support the prognostic superiority of both 24-h ambulatory blood pressure monitoring

(ABPM)79 81 andhomemonitoring81 in comparison with office measurements. Interestingly, a recent study82 demonstrated that 24-h ambulatory cuff pressures were comparable with office central pressure

measurements in the prediction of risk, although the significance of this study awaits confirmation.83 As yet, there are no data comparing the predictive value ofhomemonitoring vs. central pressure in the

prediction of risk. Ultimately, it will be necessary to evaluate the prognostic value of 24-h ambulatory central pressure.With the recent development of ambulatory central pressure systems,84,85 this is now

possible and it may be reasonable to hypothesize that 24-h central, rather than brachial ABPM would be superior in terms of risk prediction.
