Angina Pectoris and Nitroglycerine Use!

Angina pectoris is a clinical syndrome characterized by chest discomfort, usually described as a pressure, heaviness, tightness, squeezing, burning, or choking sensation. In some patients, the discomfort can be either localized to or radiates to the arms, neck, jaws, or upper back. Angina is most commonly caused by reduced myocardial perfusion due to coronary artery […]

Real-Life Observations of Clinical Outcomes With Rhythm- and Rate-Control Therapies for Atrial Fibrillation: RECORDAF

Authors: Camm AJ, Breithardt G, Crijns H, et al. Citation: J Am Coll Cardiol 2011;58:493-501. Study Question: What are the outcomes of rhythm- and rate-control strategies for atrial fibrillation (AF) in clinical practice? Data from 5,604 patients (mean age 66 years) enrolled in a longitudinal AF registry were analyzed upon enrollment and at 6 and […]

Dronedarone trial suspended due to CV events in permanent atrial fibrillation

Sanofi, maker of dronedarone (Multaq), has suspended its phase 3b trial of its antiarrhythmic drug due to an increase in cardiovascular events seen in patients randomized to dronedarone. The PALLAS trial was testing the drug in patients with permanent atrial fibrillation (AF) and at least one other cardiovascular disease risk factor; at present, dronedarone is […]

Tilt Table Test

What you need to know about the Tilt Table Test What is a tilt table test? The tilt table test (also called a passive head-up tilt test or head upright tilt test) records your blood pressure and heart rate on a minute-by-minute basis while the table is tilted in a head-up position at different levels. […]

About the Heart’s Electrical System

About the Heart’s Electrical System When most people think of the heart, they think of the arteries of the heart, or of the heart muscle and valves. But the heart also has a complex electrical system that coordinates the rhythm. Abnormalities in the heart’s electrical system can lead to arrhythmias – causing the heart to […]

Cardiac Resynchronization Therapy (CRT)

Cardiac Resynchronization Therapy (CRT) Cardiac resynchronization therapy (CRT) is a device-based therapy for patients with damaged heart muscles, electrical timing abnormalities, and symptomatic heart failure. Also known as biventricular pacing (bi-V pacing), CRT can be accomplished with either a pacemaker or an ICD (see pacemaker and ICD sections for further details on these procedures). CRT […]

Implantable Cardioverter Defibrillators (ICDs)

Implantable Cardioverter Defibrillators (ICDs) An “implantable defibrillator” is more correctly called an “implantable cardioverter defibrillator” or ICD for short. ICDs are intended for patients who have had or are at high risk for developing life-threatening rapid heart racing attacks called ventricular tachycardia (VT) or ventricular fibrillation (VF) that can lead to death. An ICD is […]

Palpitations

Palpitations Palpitations are a common problem that is often referred to a cardiologist for further investigation. Patients typically describe a sense that the heart is skipping or racing. This may be accompanied by shortness of breath, chest pain, and/or lightheadedness – or rarely, loss of consciousness. The sensation of palpitations can be caused by a […]

Coronary Angioplasty (PCI)

Definition Coronary angioplasty (AN-jee-o-plas-tee), also called percutaneous coronary intervention (PCI), is a procedure used to open clogged heart arteries. Angioplasty involves temporarily inserting and blowing up a tiny balloon where your artery is clogged to help widen the artery. Angioplasty is often combined with the permanent placement of a small wire mesh tube called a […]

Electrical Cardioversion

Electrical Cardioversion is a procedure carried out to restore a normal cardiac rhythm in selected patients whose heart rhythm is abnormal. It involves the controlled delivery of energy through the chest wall in order to “electrically reset” the heart. Most scheduled cardioversions are done for patients with atrial fibrillation (AF) or atrial flutter (AFL). Sometimes, […]
