Summary
Intensive care patients with arrhythmias like atrial fibrillation and ventricular tachyarrhythmias often benefit from antiarrhythmic drugs and defibrillation. Amiodarone is a key treatment for ventricular tachyarrhythmias and cardiac arrest.
Area of Science:
- Cardiology
- Intensive Care Medicine
- Electrophysiology
Background:
- Arrhythmias such as atrial fibrillation (AF) and ventricular tachyarrhythmias (VTA) are common in intensive care patients.
- Diagnosis often relies on physical examination, response to interventions, and electrocardiography.
Purpose of the Study:
- To review current treatment strategies for typical arrhythmias encountered in intensive care.
- To highlight effective pharmacologic and electrical therapies for various tachyarrhythmias.
Main Methods:
- Review of antiarrhythmic drug efficacy for AF and atrial flutter (Aflut).
- Evaluation of treatments for VTA, including amiodarone.
- Discussion of defibrillation strategies for cardiac arrest due to VTA.
Main Results:
- Amiodarone shows high conversion rates (up to 80%) for AF and is the drug of choice for VTA.
- Ibutilide demonstrates significant efficacy in converting AF and Aflut to sinus rhythm (SR).
- Early defibrillation with automatic external defibrillators (AEDs) improves survival rates for VTA-related cardiac arrest.
Conclusions:
- Pharmacologic and electrical cardioversion are crucial for managing intensive care unit arrhythmias.
- Amiodarone and ibutilide are effective antiarrhythmic agents.
- Public access defibrillation and advanced life support are vital for improving outcomes in cardiac arrest.

Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...

Dysrhythmia management involves a multifaceted approach, incorporating pharmacological treatments, medical procedures, surgical interventions, lifestyle modifications, and patient education.Pharmacological ManagementAntiarrhythmic Drugs:Class I (Sodium Channel Blockers): This class includes quinidine and procainamide, which reduce the speed of impulse conduction in the heart, stabilize the cardiac membrane, and control arrhythmias. Quinidine and procainamide are Class IA agents that prolong the...
01:29Disturbances in Heart Rhythm
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.

01:20Antiarrhythmic Drugs: Class IV Agents as Calcium Channel Blockers
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...

01:12Antiarrhythmic Drugs: Class III Agents as Potassium Channel Blockers
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 the heart's...
01:28Mechanism 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.
