Exercise Stress Test01:26

Exercise Stress Test

177
Introduction
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.

Electrocardiogram01:29

Electrocardiogram

2.2K
An electrocardiogram (ECG or EKG) is a critical diagnostic tool that records the electrical signals produced by the heart during each heartbeat. This recording is achieved through electrodes placed strategically on the arms, legs, and chest. The electrocardiograph amplifies these signals and produces 12 distinct tracings, offering a comprehensive understanding of the heart's electrical activity.
Three major waveforms are present in a typical ECG recording: the P wave, the QRS complex, and...

Holter Monitor: 24-Hour Monitoring

3
Holter monitoring is a continuous electrocardiography (ECG) recording that tracks the heart's electrical activity over an extended period, generally 24 to 48 hours. This noninvasive diagnostic tool detects irregular heart rhythms that may not be captured during a standard ECG performed in a clinical setting.DeviceThe Holter monitor is a portable, small device connected to several electrodes on the patient's chest. These electrodes detect the heart's electrical signals and transmit them to the...

Pulse rhythm01:30

Pulse rhythm

769
Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

Area of Science:

  • Cardiology
  • Biomedical Engineering
  • Sports Medicine

Background:

  • Limited comparative studies exist for wearable single-lead ECG devices versus standard multi-lead ECG during exercise.
  • Wearable ECGs are increasingly used, necessitating validation in clinical settings.

Purpose of the Study:

  • To validate the accuracy of a wearable single-lead ECG monitor for heart rate (HR) metrics during graded exercise tests (GXTs).
  • To compare the performance of wearable single-lead ECGs with conventional multi-lead ECGs during GXTs.

Main Methods:

  • A cohort of 50 patients underwent simultaneous GXT using both wearable single-lead and conventional multi-lead ECGs.
  • Intraclass correlation coefficient and Bland-Altman analysis were used to quantify concordance.

Main Results:

  • Generally consistent minimum and average HR readings were observed between devices.
  • Strong agreement was found for ventricular and supraventricular ectopic beats.
  • Sufficient agreement for HR measurements across GXT stages, though Total QRS and Maximum RR agreement was insufficient.
  • Standard multi-lead ECGs showed higher noise levels, though not statistically significant.

Conclusions:

  • Wearable single-lead ECG devices reliably monitor HR and detect abnormal beats during exercise.
  • These devices present a viable alternative to traditional multi-lead ECG systems for exercise testing.
