Ventricular ectopics, also known as premature ventricular contractions (PVCs), are abnormal heartbeats that originate in the ventricles rather than the atria. They occur when an extra electrical impulse causes the ventricles to contract prematurely, which can lead to a feeling of a skipped heartbeat or palpitations. While often benign, frequent PVCs can indicate underlying heart issues and may require further evaluation. Factors such as stress, caffeine, or Heart disease can contribute to their occurrence.

What are supra ventricular ectopics?
Supraventricular ectopics are premature heartbeats that originate from the atria or the atrioventricular (AV) node, rather than the ventricles. They occur when an abnormal electrical impulse triggers a heartbeat earlier than expected in the heart's rhythm. These ectopic beats can lead to palpitations but are often benign and may not require treatment unless they are frequent or symptomatic. In some cases, they can indicate underlying heart conditions, so medical evaluation may be necessary if they occur frequently.
What does inadequate ventricular systole mean?
It is a defective ventricular contraction.
What does a ventricular shunt relieve?
A ventricular shunt relieves hydrocephalus
When does Isovolumetric relaxation and ventricular filling take place?
Ventricular Diastole
Does ventricular pressure increase the fastest during ventricular filling?
yes
Which would produce the most life-threatening condition atrial flutter ventricular flutter atrial fibrillation or ventricular fibrillation?
Ventricular fibrillation, since this pumps blood to the rest of the body.
During ventricular systole is ventricular pressure increasing or decreasing?
increasing! :D
What effect does atropine have on heart rate?
Ventricular fibrillation, and supraventricular or ventricular tachycardia.
What is the difference between Left Ventricular Hypertrophy and Left Ventricular Dysfunction?
LVH (Left Ventricular Hypertrophy) is (anatomical) structural condition and status of the heart, while Left Ventricular Dysfunction is disturbance in physiological functions and status of heart.
What cardiac arrhythmia is fatal unless reversed?
Cardiac arrhythmia is usually fatal unless reversed by electric defibrillation. Cardiac arrhythmia is also sometimes referred to as ventricular fibrillation.
