Summary
Cardioneuroablation (CNA) effectively treats functional bradyarrhythmia by selectively ablating AV node ganglia. This procedure restored AV conduction in a patient, showing lasting results with low risk.
Area of Science:
- Cardiology
- Electrophysiology
- Medical Devices
Background:
- Symptomatic advanced atrioventricular (AV) block requires effective treatment.
- Functional bradyarrhythmia necessitates interventions beyond addressing reversible causes or intrinsic conduction system disease.
Observation:
- A 40-year-old woman presented with symptomatic advanced AV block.
- Cardioneuroablation (CNA) was performed after excluding other causes.
Findings:
- Selective ablation of AV node-related ganglia in the left atrium restored AV conduction.
- The restored AV conduction remained stable over a 2-year follow-up period.
Implications:
- Cardioneuroablation (CNA) presents a viable, effective, and low-risk therapeutic option for functional bradyarrhythmias.
- The findings support CNA as a treatment for bradyarrhythmias of varying severity.

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.

01:22Antiarrhythmic Drugs: Class I Agents as Sodium Channel Blockers
1.2K
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.

01:20Antiarrhythmic Drugs: Class IV Agents as Calcium Channel Blockers
763
Class IV antiarrhythmic drugs, such as verapamil and diltiazem, block calcium channels. They primarily affect the heart, slowing the conduction in calcium-dependent tissues like the SA and AV nodes. These drugs manage reentrant supraventricular tachycardia (SVT) and reduce ventricular rate in atrial flutter/fibrillation.
Verapamil, a calcium channel blocker, inhibits calcium movement across myocardial cell membranes and vascular smooth muscle. This results in the dilation of coronary and...

01:24Antiarrhythmic Drugs: Class II Agents as β-Adrenergic Blockers
705
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...

01:12Antiarrhythmic Drugs: Class III Agents as Potassium Channel Blockers
892
Class III antiarrhythmic drugs are a group of medications that can prolong action potentials in the heart. They achieve this by blocking potassium channels or enhancing inward currents from sodium channels. However, these drugs have a unique property of "reverse use-dependence," which is most pronounced at slower heart rates and can lead to torsades de pointes—a specific type of arrhythmia. However, it is essential to note that excessive QT interval prolongation—a measure of...

01:14Decreased pulse rate
531
Bradycardia is a medical condition in which the heart rate is slower than normal. It occurs when the heart's natural pacemaker, the sinus node, generates slower electrical impulses than the standard rhythm. In adults, bradycardia is diagnosed when the pulse rate falls below 60 beats per minute, indicating a deviation from the normal heart rate range.
