Ventricular Tachycardia – Classification

Ventricular Tachycardia – Classification Ventricular tachycardia is a common arrhythmia. The manifestations include mild symptoms of palpitation to sudden death. In next few blog posts, we will try to understand the basics of ventricular tachycardia/fibrillation and we will discuss management of these arrhythmias. Definition: Ventricular arrhythmias are defined as arrhythmias that originate below the bifurcation of […]

Primary prevention ICD in Nonischemic cardiomyopathy

There is a recent online first article in NEJM  ( Defibrillator Implantation in Patients with Nonischemic Systolic Heart Failure – DANISH Study). The study is summarized below: Summary: The benefit of an implantable cardioverter–defibrillator (ICD) in patients with symptomatic systolic heart failure caused by coronary artery disease has been well documented. However, the evidence for […]

Myocardial Infarction- Third Universal definition and classification

Definition of myocardial infarction Criteria for acute myocardial infarction : The term acute myocardial infarction (MI) should be used when there is evidence of myocardial necrosis in a clinical setting consistent with acute myocardial ischaemia. Under these conditions any one of the following criteria meets the diagnosis for MI: • Detection of a rise and/or […]

AMBITION: Initial Use of Ambrisentan plus Tadalafil in Pulmonary Arterial Hypertension

Data on the effect of initial combination therapy with ambrisentan and tadalafil on long-term outcomes in patients with pulmonary arterial hypertension are scarce. METHODS In this event-driven, double-blind study, patients were randomly assigned, in a 2:1:1 ratio, participants with World Health Organization functional class II or III symptoms of pulmonary arterial hypertension who had not previously […]

Approach to Arrhythmia part 1: Bradycardia

Approach to Arrhythmia part 1: Bradycardia Bradycardia is defined as heart rate <60/min. To understand the cause of bradycardia we have to understand the structures involved in the production and conduction of cardiac impulse. The normal cardiac structures involved in electrical activity of the heart are 1. SA node- It is the pacemaker of the […]

Revised Jones Criteria for Acute Rheumatic Fever – 2015 guideline

Acute rheumatic fever remains a serious healthcare concern for the majority of the world’s population despite its decline in incidence in Europe and North America. This statement reviews the historic Jones criteria used to diagnose acute rheumatic fever in the context of the current epidemiology of the disease and updates those criteria to also taking into account the […]

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 […]

CAROTID ARTERY STENTING: SILK ROAD PROCEDURE

SILK ROAD PROCEDURE Innovation in carotid artery stenting. Watch this nice animation to understand the concept (downloaded from: http://www.silkroadmedical.com/silkroad-procedure/how-it-works/) A recently presented trial (ROADSTER IDE) shows promising results for this new technique

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 […]
