Dysrhythmias IV: Characteristics of Bradyarrhythmias01:18

Dysrhythmias IV: Characteristics of Bradyarrhythmias

708
Bradyarrhythmias are cardiac rhythm disorders characterized by a slower-than-normal heart rate, typically defined as fewer than 60 beats per minute. Some of which are discussed here:Sinus BradycardiaSinus bradycardia presents a heart rate lower than 60 beats per minute, with a regular rhythm originating from the SA node. The ECG typically shows normal P waves preceding each QRS complex, a normal PR interval (0.12 to 0.20 seconds), and a normal QRS duration (0.06 to 0.10 seconds).First-Degree AV...

Ischemic Heart Disease: Overview

3.7K
Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and...

Antiarrhythmic Drugs: Class IV Agents as Calcium Channel Blockers

2.5K
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...

Area of Science:

  • Cardiology
  • Neurology
  • Vascular Medicine

Background:

  • Cardiac and cerebrovascular diseases are leading causes of death and disability worldwide.
  • Thromboembolisms, often arising from cardiac arrhythmias, are significant contributors to ischemic stroke.
  • Understanding the diverse etiologies of stroke is crucial for effective prevention and treatment.

Observation:

  • This study details a rare clinical case.
  • The patient presented with multicentric ischemic stroke.
  • The underlying cause identified was Mobitz type II atrioventricular block.

Findings:

  • Mobitz type II atrioventricular block, a specific type of heart rhythm disturbance, was directly linked to the occurrence of multiple ischemic strokes.
  • This case demonstrates an unusual but significant pathway from cardiac electrical abnormality to cerebral infarction.
  • The findings underscore the importance of considering cardiac causes in patients with unexplained stroke.

Implications:

  • Highlights the need for thorough cardiac evaluation in patients experiencing ischemic stroke, particularly those with atypical presentations.
  • Suggests that early detection and management of atrioventricular blocks may prevent severe cerebrovascular complications.
  • Contributes to the understanding of thromboembolism formation in the context of specific cardiac conduction abnormalities.
