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 – 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 […]

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 […]

Calculation of heart rate from ECG

Calculation of heart rate from ECG In my last post I have enumerated the points for studying an ECG. The first step is to check the calibration and paper speed. Then comes the calculation of heart rate. There are various methods of calculating the heart rate from ECG. We will discuss about the most commonly […]

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 […]
