What is carditis of the heart? What is the ECG? What is cardiac preload? What is a ventricular couplet? What is another name for the left atrioventricular valve? What is the OM coronary artery? What are cardiology Q waves? What is the QRS complex?
What is ventricular resting potential?Question:What is ventricular resting potential?Chambers of the Heart:The ventricles of two of the four chambers of the heart. The other two chambers, found above the ventricles, are the atria. Blood flows through the heart via contraction of these chambers.An...
Ventricular tachycardia:In this, the heart abnormally contracts faster (>100 beats/minute) due to abnormal electrical activity in the ventricle (heart’s large chamber) causing the heart to dysfunction. Ventricularfibrillation:Regulation of the heartbeat is interrupted by multiple abnormal impulses genera...
617 WHAT IS THE NATURAL HISTORY OF HEART FAILURE DUE TO LEFT VENTRICULAR SYSTOLIC DYSFUNCTION IN THE ERA OF EVIDENCE BASED MEDICINE?Objective: Heart failure (HF) is a complex clinical syndrome that requires a challenging diagnosis. We looked at the long term outcome of HF patients refer...
Ventricular fibrillationis a heart rhythm issue in the heart's lower ventricles. It is a misfire in the electrical signals of the heart that cause the ventricles to flutter randomly. If normal heart rhythm is not restored, it can lead to death. Ventricular fibrillation is most found in those...

flow, the antrioventricular node slows this signal so that the ventricles, or lower chambers of the heart, are not triggered to contract until the atria, the upper chambers, have fully contracted. The reduction in speed of the signal's movement is usually as little as one-tenth of a ...
Ventricular fibrillationis the abnormal heart rhythm most often responsible for sudden cardiac arrest. It is characterized by a rapid but irregular heartbeat. Ventricular tachycardiais also a heart rhythm disorder (arrhythmia), caused by abnormal electrical signals in the lower chambers of the heart (...
In cardiac arrest, the heart stops beating and needs to be restarted. While a heart attack is a circulation problem, cardiac arrest is an electrical problem
What is SCA? SCA is an electrical problem with the heart that causes a dangerously fast heart rhythm (ventricular fibrillation). The rapid, irregular heart rhythm causes the heart to quiver rather than pump. When the heart stops pumping blood, oxygen cannot reach the body and brain. If not ...
