Premature ventricular contractions (PVC’s), the lower chambers of the heart contract without receiving the appropriate signal from the upper chambers of the heart. This causes the ventricles to contract prematurely, which..

Read MoreImplantable Cardioverter Defibrillator, or ICD , is a battery-powered device that keeps track of your heartbeat and can deliver an electrical shock that will allow ventricular muscle fibrillation to return..
Read MoreThe impulse starts at the sinoatrial node (SA node) the hearts natural pacemaker.⠀ ⠀ The impulse travels through the internodal pathways to the atrioventricular node (AV node). ⠀ From the..
Read MoreAtrial fibrillation (AF), a type of irregular heartbeat. Having AF means that blood clots are more likely to form in your heart, increasing your risk of stroke. Atrial Fibrillation is..
Read MoreRVOT Ventricular Tachycardia, During Right Ventricular Outflow Tract (R.V.O.T.) Ventricular Tachycardia, abnormal signals originate in the right ventricle near the pulmonary valve, also known as the right ventricular outflow tract...
Read MoreBradycardia is a type of heart arrhythmia. In bradycardia, the heartbeat is slow, less than sixty beats per minute. It may be caused by a problem with the pacemaker of..
Read MoreAtrioventricular Nodal Reentry Tachycardia, or AVNRT , is a type of heart arrhythmia, or irregular heartbeat. The most common type of SVT is AVNRT. In AVNRT, electrical signals reenter the..
Read MoreVentricular Tachycardia is a heart arrhythmia, or irregular heartbeat. In ventricular tachycardia, abnormal electrical pulses in the lower chambers, or ventricles, disrupt the normal firing of the SA node, causing..
Read MoreThe heartbeat is controlled by the electrical system of the heart. This system is made of several parts that tell the muscle of the heart when to contract. The SA..
Read MoreSudden cardiac arrest (SCA) is an event caused by a problem with the heart’s “electrical” system. SCA occurs when the heart suddenly stops beating. The heart’s electrical system sends signals to..
Read MoreSupraventricular Tachycardias include a group of heart arrhythmias, or irregular heartbeats that originate in the atria. In each of these conditions, electrical signals begin in the atria, sending abnormal signals..
Read MoreOverdrive Suppression We have here in Figure 1 what is most likely an AV nodal reentrant tachycardia (AVNRT). Could it possibly be an AV reentrant tachycardia with orthodromic conduction through..
Read MoreOften we come upon pauses on 12-lead ECGs and rhythm strips. Some of these pauses have durations that we are simply unable to justify while others are easier to comprehend...
Read MoreAbstract Cardiac amyloidosis (CA) is an infiltrative cardiomyopathy caused by the extracellular deposition of amyloid fibrils in the myocardium. Although cardiac amyloidosis patients primarily present with heart failure symptoms, arrhythmias..
Read MoreOne of the first things I try to teach the participants in my classes is the meaning of the term atrioventricular block – commonly abbreviated as “AV block.” So many..
