Insights

Smartphone ECGs provide diagnostic quality pediatric tracings for arrhythmias like supraventricular tachycardia (SVT) and atrial fibrillation (AF). Parents and patients reported high satisfaction, indicating potential for remote arrhythmia management.

Area of Science:

  • Pediatric Cardiology
  • Medical Device Technology
  • Digital Health

Background:

  • Smartphone-enabled electrocardiogram (ECG) devices offer potential for remote arrhythmia assessment in pediatric patients.
  • Evaluating the diagnostic utility and user satisfaction of these devices is crucial for their clinical integration.

Purpose of the Study:

  • To assess the usefulness of pediatric ECG tracings obtained via the AliveCor smartphone device.
  • To evaluate user satisfaction with the AliveCor device in pediatric patients with arrhythmias.

Main Methods:

  • Prospective study involving pediatric patients with documented paroxysmal arrhythmias.
  • Analysis of ECG tracings reviewed by pediatric electrophysiologists.
  • Assessment of user satisfaction through completed surveys.

Main Results:

  • 35 pediatric patients enrolled with various arrhythmias, including supraventricular tachycardia (SVT) and atrial fibrillation (AF).
  • 96% of 238 transmitted ECG tracings were of diagnostic quality.
  • High user satisfaction reported: 98% found tracings easy to obtain and transmit, 98% felt more comfortable managing arrhythmias, and 93% desired continued use.

Conclusions:

  • Smartphone-enabled ECG devices generate diagnostic-quality tracings in children.
  • Extremely positive user satisfaction suggests feasibility for remote management.
  • Potential to reduce emergency department visits and healthcare costs for pediatric arrhythmia management.

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...

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...

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...

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...
