Disturbances in Heart Rhythm01:29

Disturbances in Heart Rhythm

2.3K
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 heart...

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias

383
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...

Dysrhythmias IV: Characteristics of Bradyarrhythmias

394
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...

Area of Science:

  • Cardiology
  • Vascular Surgery
  • Interventional Radiology

Background:

  • Left-sided catheter ablation necessitates anticoagulation to prevent thromboembolic events.
  • Activated Coagulation Time (ACT) is the standard method for monitoring anticoagulation during these procedures.

Observation:

  • A specific case encountered erroneous Activated Coagulation Time (ACT) readings.
  • These inaccurate results posed a challenge in confirming adequate anticoagulation.

Findings:

  • The study identifies limitations of ACT in certain clinical scenarios.
  • Alternative methods for monitoring anticoagulation were reviewed to address the observed inaccuracies.

Implications:

  • Accurate anticoagulation monitoring is critical for patient safety during catheter ablation.
  • Exploring alternative methods can improve procedural safety and outcomes.
  • This case underscores the need for vigilance and backup strategies in anticoagulation management.
