Which of the following parts of an ECG represents the depolarization of the atria? a) The ST interval b) The P-wave c) The QRS-complex d) The T-wave e) The PR-interval How is the QT segment related to arterial pulse pressure? A patient's ECG recording shows a consistent patter...
Analysis of in situ ECG recordings showed a markedly shortened QT interval and decreased QRS amplitude with increased heart rate. We also observed increased oxidative stress and decreased antioxidant defense characterized by decreases in serum total thiol level and attenuated paraoxonase and arylesterase ...
