Pulse rhythm01:30

Pulse rhythm

973
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...

Electrocardiogram01:29

Electrocardiogram

3.6K
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

408
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...

Electrocardiogram Fundamentals

919
Introduction
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
Parts of an ECG
An ECG utilizes electrodes on the skin...

Dysrhythmias V: Evaluating Dysrhythmias01:30

Dysrhythmias V: Evaluating Dysrhythmias

132
Dysrhythmias, also known as arrhythmias, are disturbances in the heart's rhythm that range from benign to life-threatening. A thorough evaluation is crucial for appropriate management and involves a comprehensive medical history, physical examination, and various diagnostic tests.Medical HistorySymptoms: Collect detailed information on palpitations, dizziness, syncope, chest pain, and fatigue. Note their onset, frequency, and triggers.Previous Cardiac Issues: Document any history of heart...

Area of Science:

  • Cardiology
  • Biomedical Engineering
  • Health Informatics

Background:

  • Insertable cardiac monitors (ICMs) are crucial for diagnosing arrhythmias remotely.
  • Manual review of electrograms (EGMs) from ICMs is time-consuming and labor-intensive.
  • Efficient data triage is needed to optimize arrhythmia diagnosis.

Purpose of the Study:

  • To assess the clinical impact of prioritizing key electrograms (EGMs) for review.
  • To determine if a focused EGM review strategy affects diagnostic timelines.

Main Methods:

  • Retrospective analysis of Abbott Confirm Rx™ ICM data with over 90 days of transmission.
  • EGMs were adjudicated as true or false positives (TP, FP).
  • Key EGMs were selected based on arrhythmia type, ventricular rate, and episode duration, with up to 3 per day.

Main Results:

  • Key EGM selection reduced the overall EGM review burden by 55%.
  • True positive (TP) days were minimally reduced (0.0-2.1%) across arrhythmia types.
  • 99% of patients with true arrhythmias received a diagnosis on the same day as with full EGM review.

Conclusions:

  • Prioritizing key EGMs substantially decreases the review burden.
  • This strategy accelerates clinical workflow without compromising diagnostic timelines for arrhythmias.
  • Implementation in patient care networks can improve efficiency for ICM data analysis.
