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...

Mechanism of Cardiac Arrhythmias

Mechanism of Cardiac Arrhythmias

Arrhythmias are irregular heart rhythms occurring when the heart's electrical impulses become abnormal. These disturbances can lead to various symptoms, depending on their severity and the underlying cause. Some common factors contributing to arrhythmias include hypoxia, ischemia, electrolyte imbalances, excessive catecholamine exposure, drug toxicity, and muscle overstretching. Arrhythmias can be classified into two main types based on the rate and site of origin of abnormal heart rhythms.

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...

Background:

Cardiac implantable electronic devices (CIEDs) can malfunction due to electromagnetic interference from various sources.
Abandoned pacemakers, even when deactivated, pose a potential risk of unintended reactivation and interaction with active CIEDs.

Observation:

A 79-year-old male with an active leadless pacemaker and an abandoned abdominal pacemaker experienced presyncope.
The abandoned pacemaker self-activated due to end-of-life mode, inhibiting the active pacemaker and causing intermittent loss of myocardial capture.

Findings:

Reactivation of an abandoned pacemaker led to critical interaction with an active pacemaker, resulting in symptoms.
Temporary management involved adjusting the active pacemaker's settings, but final resolution required explantation of the abandoned device.

Implications:

This case underscores the critical importance of explanting deactivated abandoned cardiac pacemakers to prevent potentially life-threatening interactions.
Healthcare providers should be vigilant about the risks associated with abandoned CIEDs and ensure their complete removal.
Proactive management of abandoned CIEDs is essential for patient safety and optimal device therapy.
