What happens if heart rate response with exercise is blunted? Cardiac output is the product of stroke volume and heart rate. It will not rise sufficiently with exercise
Pulseless electrical activity Any rhythm without a pulse can be called a pulseless electrical activity. It is also sometimes called electromechanical dissociation. Usually it is a fast ventricular
Idiopathic Fascicular Ventricular Tachycardia (Belhassen’s Ventricular Tachycardia) Idiopathic fascicular ventricular tachycardia is unique in that it has a relatively narrower QRS width and it responds to verapamil. It
What is sick sinus syndrome? Sick sinus syndrome is an abnormality of the natural pacemaker of the heart, the sino-atrial node, also known as sinus node and SA
Sick sinus syndrome Sick sinus syndrome: A disorder in which the natural pacemaker of the heart (sinoatrial node) is abnormal, usually producing bradycardia and long pauses which can
Tachy-brady syndrome Tachy-brady syndrome: A condition in which tachycardia alternates with bradycardia. Classical manifestation of sick sinus syndrome.
Tachyarrhythmia Tachyarrhythmia: Arrhythmia (abnormal rhythm) with a fast heart rate. Examples are sinus tachycardia, supraventricular tachycardia and ventricular tachycardia.
Torsades des pointes Torsades des pointes: Polymorphic ventricular tachycardia with prolongation of QT interval. The tachycardia complexes appear to “twist around a point”.
