|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


lateral leads and deep S waves in septal leads,--> think LVH
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\




What is systole? - CORRECT ANSWERS ✔✔myocardium contracts and forces
|\ |\ |\ |\ |\ |\ |\ |\ |\


blood out of left ventricle
|\ |\ |\ |\ |\




What is diastole? - CORRECT ANSWERS ✔✔left ventricle myocardium relaxes
