How does chronic aortic stenosis lead to left ventricular hypertrophy? Chronic aortic stenosis leads to left ventricular hypertrophy bc of increased workload of pumping blood through a narrow opening. The left atrium can also enlarge but mainly causes left ventricular hypertrophy. The right ventricle will remain normal for a period of time. That's why LHF happens first then leads to RHF. Chronic mitral stenosis will cause enlargement in which area? Left atria hypertrophy. In pt with Mitral v...

Relias Assessments Assistance Material DYSRHYTHMIAS EKG interpretation One of the most useful and commonly used diagnostic tools is electrocardiography (EKG) which measures the heart's electrical activity as waveforms. An EKG uses electrodes attached to the skin to detect electric current moving through the heart. These signals are transmitted to produce a record of cardiac activity. Arrhythmia or dysrhythmia are disturbances in the normal cardiac rhythm of the heart which occurs as a result ...
