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 makes the contraction less effective at pumping blood. After a compensatory pause, the next beat is more effective. PVC’s can..

Implantable 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 to a normal heartbeat. Cardiologist may recommend an ICD after an episode of arrhythmic sudden cardiac death, if severe heartfailure..

The 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 AV node the impulse then travels down the bundle of His to both left and right bundle branches. ⠀ Finally..

Atrial 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 a heart arrhythmia in which abnormal electrical signals begin in the atria (or top chambers) of the heart. The most..

RVOT 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. RVOT ventricular tachycardia can be seen on an electrocardiogram. A rapid heartbeat does not give the heart enough time to..

Bradycardia 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 the heart, the SA node, which produces the electrical signal that begins the heartbeat in the upper chambers. Bradycardia may..

Atrioventricular 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 heart due to both rapid and slow electrical impulses moving through an abnormal AV node. The result is a fast..

Ventricular 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 the heart to beat rapidly. These signals can be seen in an Electrocardiogram or ECG. A rapid heartbeat does not..
