2. 2. The heart rate or, otherwise stated, the duration of the Q-T interval. The effect of a diphasic form of the initial ventricular complex is considered. The effect upon the RS-T segment of the presence of the electrical forces which give rise to the ventricular gradient is discussed...
If you have a faster-than-normal heart rate (your heart beats more than 100 times per minute), you have what doctors call tachycardia. It’s not always a bad thing. Exercise, for example, can push your heart rate above 100 bpm. However, you may require medication to slow your heart r...
Sample: Atrial Fibrillation “A-Fib” Rhythm: Irregularly Irregular Rate: Atrial rate is fast and irregular, ventricular rate varies P waves: None, “f” or “fib” waves PR Interval: None QRS Complex: “Normal” (0.08-0.12 seconds) Multiple areas of reentry within the atria or from ...
Yourheartrate is a measure of how fast your heart beats and is also an important indicator of good health. Your doctor will always make it a point to measure your heart rate whenever you visit him for your routine health checkup or any health-related problem. While the heart rate is rout...

training have more efficient heart muscles. The capacity of their left ventricles has increased and the ventricular muscles have become stronger, leading to an increased stroke volume. This increased stroke volume can be observed as a lowerresting heart rateas well as a lower training heart rate....
These alterations in HRV were associated with significantly increased heart rate and reduced right ventricular end-diastolic volume. Although there was a small but significant increase in cardiac output with exposure to PS, HRV was unchanged. These data indicate that there was a relative shift in ...
While useful to display overall trends in the literature for the athletes heart, the aforementioned meta-analysis was therefore not included in this study. Normal thickness of the compact left ventricular myocardium in adults CMR acquisition parameters Normal values of the thickness of the compact LV...
