Prompt treatment of broad complex tachycardias is crucial but challenging. This case highlights posterior fascicular ventricular tachycardia, a verapamil-sensitive condition often misdiagnosed.
Area of Science:
- Cardiology
- Emergency Medicine
- Electrophysiology
Background:
- Broad complex tachycardias (BCTs) present a diagnostic challenge in emergency settings.
- Accurate diagnosis of BCTs is vital for effective patient management and outcomes.
Observation:
- A case of posterior fascicular ventricular tachycardia (PFVT) is presented.
- PFVT is an idiopathic ventricular tachycardia occurring in patients without coronary artery disease.
Findings:
- Posterior fascicular ventricular tachycardia is sensitive to verapamil.
- Differential diagnosis between PFVT and supraventricular tachycardia with aberrancy is discussed.
Implications:
- This case emphasizes the importance of considering PFVT in the differential diagnosis of BCTs.
- Recognition of verapamil-sensitive PFVT can guide prompt and appropriate emergency treatment.
- Improved diagnostic strategies for BCTs can enhance patient care in emergency departments.

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, and...
