Neither, theoretically the two ventricles contract simultaneously. The coronary arteries begin as two holes just above the leaflets of the aortic valve. During systole the leaflets block the coronary arteries and prevent blood flow to them. It is during diastole (of both ventricles) that blood returns to the coronary vasculature.
Most ventricular tachycardias are associated with serious heart disease such as coronary artery blockage, cardiomyopathy, or valvular heart disease.
Coronary arteries. The orifice of the coronary arteries are located on proximal part of the ascending aorta, and there are two orifices branching into the left and right coronary arteries.The marginal, anterior and ventricular arteries provide the cardiac muscle with oxygenated blood.The coronary arteries are the major vessels bringing blood to the heart muscle. The are the left and right coronary arteries, the left having a common trunk followed by the circumflex and anterior descending branches. Each of these give off side branches which bring blood and hence oxygen to the heart muscle. Coronary arteries fill during diastole.There is a right coronary artery and the left coronary artery. In total there are four coronary arteries.
The coronary sinus runs in the posterior coronary sulcus. In the anterior coronary sulci the stems of the coronary artery run. The circumflex branch of the left and the extension of the right coronary artery that becomes the posterior descending artery run around the coronary sulcus from front to back
Diastole is when a given chamber of the heart is relaxing. There is atrial diastole and ventricular diastole. Most of the time when talking about diastole we are referring to the ventricular because that is when we measure the diastolic (low) pressure in your systemic arteries, usually the brachial artery.

A person can trace the blood flow from the left coronary artery to the apex of the heart and to the right atrium, by following inter ventricular artery. Blood also will move through the pulmonary semi lunar valve.
Most ventricular tachycardias are associated with serious heart disease such as coronary artery blockage, cardiomyopathy, or valvular heart disease.
The interventricular septum is primarily supplied by the left anterior descending (LAD) artery, a branch of the left coronary artery. In some individuals, the posterior descending artery (PDA), which branches from the right coronary artery, may also contribute to the blood supply of the lower part of the septum. The degree of supply can vary based on the individual's coronary artery anatomy.
No, you would not be able to feel a pulse during atrial systole alone. A pulse is felt when blood is ejected from the heart into the arteries during ventricular systole, when the ventricles contract and pump blood into the aorta and pulmonary artery. Atrial systole occurs just before ventricular contraction and primarily fills the ventricles with blood, so it does not generate the pressure wave necessary to create a palpable pulse.
The right ventricle empties into the pulmonary arteries and the left ventricle empties into the aorta.
During ventricular systole, blood is ejected from the ventricles into the arteries. The right ventricle pumps deoxygenated blood into the pulmonary artery, directing it to the lungs for oxygenation, while the left ventricle sends oxygenated blood into the aorta, distributing it throughout the body. This movement occurs due to the contraction of the ventricular muscles, which increases pressure and forces the blood out of the heart.
