…source and reflectors move towards each other, sound waves are compressed and vice versa . Erythrocytes reflect ultrasound waves. Because erythrocytes are small, round and have…

…metabolism. Cardiac cells are highly capable of matching the supply and demand of ATP; increased cardiac workload results in increased ATP production and vice versa…

…as heart rate increases and vice versa. Thus, long cycles (i.e. long RR intervals) are associated with long refractory periods and short RR intervals…

…As the heart rate increases, the QT interval decreases and vice versa. The physiological purpose of this phenomenon is to allow for faster cardiac cycles…

…association between ECG changes and the risk of arrhythmia is weak. Hence, arrhythmias may occur in the absence of ECG changes and vice versa (i…
