Holter Monitor: 24-Hour Monitoring

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...

Pulse rhythm

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 muscle...

Summary

The implantable loop recorder effectively diagnosed cardiac issues in children, resolving symptoms in nearly half of patients. It accurately identified arrhythmias in those with persistent syncope or palpitations.

Area of Science:

Pediatric Cardiology
Electrophysiology
Medical Devices

Background:

Syncope and palpitations are common presenting complaints in pediatric cardiology.
Accurate diagnosis of cardiac arrhythmias is crucial for effective management in children.

Purpose of the Study:

To evaluate the utility and outcomes of implantable loop recorder (ILR) use in pediatric patients.
To assess the diagnostic yield and complication rates of ILRs in children presenting with unexplained syncope, seizures, or palpitations.

Main Methods:

A retrospective study was conducted on 34 children who received 38 ILR implantations between September 1998 and October 2005.
Patient demographics, presenting complaints, diagnostic findings, symptom resolution, and complications were analyzed.

Published on: January 24, 2025

Main Results:

The primary indications for ILR implantation were syncope (76.5%), seizures (17.6%), and palpitations (5.9%).
Approximately 44.1% of patients experienced symptom resolution post-implantation.
ILRs successfully identified cardiac rhythm during symptomatic episodes in patients with persistent symptoms, revealing conditions like asystole and ventricular tachycardia.

Conclusions:

Implantable loop recorders are effective in achieving symptom resolution in nearly 50% of pediatric patients with syncope and palpitations.
While diagnostic for persistent symptoms, the complication rate associated with ILR implantation in children may be higher compared to adults.
