Summary
This summary is machine-generated.Implantable cardiac monitors (ICMs) detected arrhythmias in 25% of patients, leading to interventions for both expected and unexpected conditions like atrial fibrillation and bradyarrhythmias.
Area Of Science
- Cardiology
- Electrophysiology
- Medical Devices
Background
- Implantable cardiac monitors (ICMs) are increasingly used for diagnosing cardiac arrhythmias.
- Understanding the diagnostic yield and clinical relevance of ICMs across various patient populations is crucial.
Purpose Of The Study
- To determine the incidence of both anticipated and incidental arrhythmic diagnoses in patients with an ICM.
- To assess the clinical relevance and subsequent medical interventions prompted by ICM findings.
Main Methods
- A cohort of 119 patients with diverse ICM indications were monitored remotely across four Italian sites.
- Arrhythmia occurrences and subsequent medical actions were systematically recorded.
Main Results
- At 18 months, atrial fibrillation incidence was 36% in the AF management group. Bradyarrhythmias (42%) and asystole (23%) were common in cryptogenic stroke patients.
- No significant difference in atrial fibrillation rates was observed between cryptogenic stroke and syncope/presyncope groups.
- 25.2% of patients required medical intervention, including atrial fibrillation ablation (10.9%) and medication adjustments (10.1%).
Conclusions
- ICM implantation in a real-world, heterogeneous patient cohort led to significant medical interventions in approximately 25% of cases within a short period.
- Incidental findings, such as bradyarrhythmias in cryptogenic stroke patients and atrial fibrillation in syncope patients, frequently guided clinical management.

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...
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.
Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow...
Arrhythmias are disturbances in the heart's rhythm that lead to abnormal heartbeats. These irregularities can originate from different parts of the heart and are classified based on their origin and nature.
Types of Arrhythmias
Sinus Node Arrhythmias
Sinus Bradycardia: Originating from the sinoatrial (SA) node, sinus bradycardia involves slower impulses, resulting in a heart rate of less than 60 beats per minute (bpm). Causes include sleep, vagal stimulation, beta-blockers, hypothyroidism,...
Class I antiarrhythmic drugs are used to treat various types of arrhythmias or irregular heart rhythms. These drugs block the sodium (Na+) channels in the cardiac cells, thereby affecting the movement of electrical impulses across the heart. Class I antiarrhythmic drugs are divided into three subgroups: Class IA, Class IB, and Class IC, each with distinct mechanisms of action and effects on the heart.
Class 1A Antiarrhythmic Drugs: These drugs work by moderately blocking sodium channels,...
Adrenergic stimulation generally impacts cardiac rate and rhythm. Specifically, stimulation of the β-adrenoceptors triggers an increase in intracellular calcium ion influx and pacemaker currents, which may cause arrhythmias. Catecholamines like adrenaline also demonstrate β2-adrenoceptor-mediated hypokalemia, impacting cardiac action potential and disrupting the normal cardiac rhythm. Class II antiarrhythmic drugs are β-adrenoceptor antagonists or β-blockers, which...
