An automated external defibrillator or automatic electronic defibrillator (AED) is a portable electronic device that automatically diagnoses the life-threatening cardiac arrhythmias of ventricular fibrillation (VF) and pulseless ventricular tachycardia, [1] and is able to treat them through defibrillation, the application of electricity which stops the arrhythmia, allowing the heart to re ...
Accessory pathways are often diagnosed using an electrocardiogram, but characterisation and location of the pathway may require an electrophysiological study. Accessory pathways may not require any treatment, but those causing symptoms may be treated with medication including calcium channel antagonists , beta blockers or flecainide . [ 3 ]
Defibrillation is a treatment for life-threatening cardiac arrhythmias, specifically ventricular fibrillation (V-Fib) and non-perfusing ventricular tachycardia (V-Tach). [1] [2] A defibrillator delivers a dose of electric current (often called a counter-shock) to the heart.
Structural heart disease, such as coronary artery disease, is a common underlying condition in people who experience cardiac arrest. The most common risk factors include age and cardiovascular disease. [15] Additional underlying cardiac conditions include heart failure and inherited arrhythmias.
The scale part at the base of the mirror assesses health metrics and biomarkers including blood pressure, heart rate, body mass index, Vo2 Max (the amount of oxygen your body uses during exercise ...
An accessory "bypass tract" can avoid the AV node and its protection so that the fast rate may be directly transmitted to the ventricles. This situation has characteristic findings on ECG . [ 14 ] A congenital heart lesion, Ebstein's anomaly , is most commonly associated with supraventricular tachycardia.
