One MCQ a day- 14.04.2015

Answer to the question on 13.04.2015: Answer : A (Right ventricular outflow tract) Explanation: 12-lead electrocardiographic (ECG) morphology helps in identifying the PVC origin Left bundle branch block morphology with an inferior axis indicates an outflow tract origin of the PVCs, with a late precordial transition (>V3) pointing to an origin in the right ventricular outflow tract, and an […]

One MCQ a day: 13.04.2015

Answer to the question on 12.04.2015: Answer : A Explanation: The ECG is showing atrial fibrillation with fast ventricular rate. The important issue in this ECG is that the ventricular rate is extremely fast, reaching up to 300 bpm. AF with very fast ventricular rate is suggestive of conduction over bypass tracts. Patients with preexcited atrial […]

One MCQ a day – 12.04.2015

Answer to the question on 11.04.2015 Answer : D localizing the AP 1. Left free-wall APs are associated with positive delta waves in lead V1 and negative delta waves in leads I and aVL 2. The ECG in a patient with a manifest right-sided AP shows a negative delta wave in lead V1 and positive delta waves in […]

One MCQ a day – 11.04.2015

Answer to the question on 10.04.2015 Answer: B Accessory pathways are anomalous bypass tracts composed of working myocardial cells. Most APs insert along the mitral or tricuspid valve and are referred to as AV accessory pathways. Approximately 60% of APs insert along the mitral valve and are referred to as left free-wall pathways. About 25% insert along the septal aspect of […]

Q.  Which of the following statements about location of accessory pathways (AP) is correct? A.  10% of APs  are left free-wall pathways, 80% are septal and […]

Top 10 Cardiology Articles of the week

Top 10 Cardiology Articles of the week (02.03.2015-08.03.2015) 1. Low-Level Transcutaneous Electrical Vagus Nerve Stimulation (LLTS) Suppresses Atrial Fibrillation Conclusion: LLTS suppresses AF and decreases inflammatory cytokines in patients with paroxysmal AF. The results support the emerging paradigm of neuromodulation to treat AF. 2. Implantable Cardioverter-Defibrillator Therapy in Brugada Syndrome:A 20-Year Single-Center Experience Background: Patients […]

Simplest approach to reading the ECG. Part-1

APPROACH TO READING THE ECG ECG or EKG (the electrocardiogram) has retained its role as the first and foremost investigations for many cardiovascular diseases. ECG is absolutely mandatory for diagnosis of heart rhythm and for myocardial ischemia. It has a prominent role in the diagnosis and management planning of a variety of cardiac diseases starting […]
