New studies suggest catheter ablation could be the first-line rhythm treatment for atrial fibrillation Two studies — EARLY-AF and STOP AF First — indicate that catheter ablation, using cryoablation technology (Medtronic), could be the first-line rhythm treatment for atrial fibrillation (AF). They both showed that cryoablation was more effective at reducing recurrent episodes of AF than antiarrhythmic
WHY IS CARDIAC ARREST LIFE-THREATENING? Cardiac arrest happens when the there is an electrical problem, between the brain and the Sinus Atrial node of the heart. The heart is unable to receive the electrical impulse from the brain, that signals the heart to keep on beating. When this happens, the heart stops beating
COVID-19 can affect the heart The family of seven known human coronaviruses are known for their impact on the respiratory tract, not the heart. However, the most recent coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has marked tropism for the heart and can lead to myocarditis (inflammation of the heart), necrosis of
RESTART YOUR HEART DAY Worldwide more than 600 000 people die annually from cardiac arrest. In South Africa alone, 11 people an hour die of cardiac arrest. Globally, cardiac arrest claims more lives than colorectal cancer, breast cancer, prostate cancer, influenza, pneumonia, auto accidents, HIV, firearms, and house fires combined. 80% of ALL
What is CPR and how do I perform it? Cardiopulmonary resuscitation (CPR) is an emergency procedure that combines chest compressions with artificial ventilation in an effort to manually preserve intact brain function until further measures are taken to restore spontaneous blood circulation and breathing in a person who is in cardiac arrest. It
Cardiovascular System Every tissue in the body requires an adequate supply of oxygen, nutrients and hormones. The waste products should be removed from the tissue from time to time. These functions are carried out by the blood. The blood is pumped out by the heart into the Aorta from which it is distributed
What is Cardiogenic Shock Cardiogenic shock is a condition in which your heart suddenly can’t pump enough blood to meet your body’s needs. The condition is most often caused by a severe heart attack. Shock is divided into four main types based on the underlying cause: low volume, cardiogenic, obstructive, and distributive shock.
