Key result
Right ventricular cavity electrocardiograms in subjects with right ventricular hypertrophy and precordial qR patterns showed absent initial R waves in 4 of 6 cases compared to controls.
Why the study?
What is the electrophysiological mechanism of the Q wave in precordial ECGs overlying a hypertrophied right ventricle?
Observational (n=6)
What is the electrophysiological mechanism of the Q wave in precordial ECGs overlying a hypertrophied right ventricle?
The initial Q wave over a hypertrophied right ventricle appears to result from abnormal depolarization of the interventricular septum.
No takes yet. Share an insight, caveat, or question.
May refine qR interpretation in RV hypertrophy; leaves open validation in contemporary cohorts before changing criteria.
Fowler et al. (1952) conducted an observational in Hypertrophied right ventricle (n=6). Right ventricular cavity electrocardiograms vs. Control subjects was evaluated on Initial R wave in the right ventricular cavity. Right ventricular cavity electrocardiograms in subjects with right ventricular hypertrophy and precordial qR patterns showed absent initial R waves in 4 of 6 cases compared to controls.
