Insights

Frequent premature ventricular contractions (PVCs) are more common in patients with chronic noncardioembolic ischemic stroke. A wearable device effectively screens for arrhythmias in this population.

Area of Science:

  • Cardiology
  • Neurology
  • Medical Devices

Background:

  • Screening for arrhythmias in patients with chronic noncardioembolic ischemic stroke is currently limited.
  • Arrhythmias can increase the risk of recurrent stroke.

Purpose of the Study:

  • To investigate the prevalence of arrhythmia in patients with chronic noncardioembolic ischemic stroke.
  • To evaluate the utility of a stick-on wearable device for arrhythmia detection in this patient group.

Main Methods:

  • A prospective observational study was conducted with 176 patients with a history of noncardioembolic ischemic stroke.
  • Patients wore a stick-on wearable device for approximately 7 days to monitor for arrhythmias.
  • Patients on anticoagulant therapy were excluded from the study.

Main Results:

  • The study found a high prevalence of frequent premature atrial contractions (PACs) at 39.2% and frequent premature ventricular contractions (PVCs) at 20.5%.
  • Age and cilostazol use were identified as independent risk factors for frequent PACs.
  • Age, male sex, and cilostazol use were independently associated with frequent PVCs.

Conclusions:

  • The prevalence of frequent PVCs in patients with chronic noncardioembolic ischemic stroke is higher than in the general population.
  • A stick-on wearable device is a valuable tool for screening arrhythmias in patients with chronic noncardioembolic ischemic stroke.

Pulse rhythm01:30

Pulse rhythm

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

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

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...

Dysrhythmias V: Evaluating Dysrhythmias

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...

Correlation between ECG and Cardiac Cycle01:25

Correlation between ECG and Cardiac Cycle

The electrical signals recorded on an electrocardiogram (ECG) occur before the mechanical processes of contraction and relaxation during the cardiac cycle.
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...
