An apparently normal ECG is defined by the following [30]: 1) heart rate between 55 and 100 bpm; 2) presence of P waves in all leads, with normal morphology; 3) presence of a QRS complex following each P wave; 4) PR interval between 0.12 to 0.20 seconds; 5) QRS duration ≤ 0.12...
The interval between the onset of the P wave and the onset of the QRS is called the PR interval, which usually does not exceed 0.20 seconds. The QRS duration is from 0.08-0.10 seconds. There is an isoelectric line separating the activity of the P wave from the QRS and the QRS from ...

Isolating only superextended blinks (gt;0.5nbsp;seconds), average contact time was also significantly different (7.134nbsp;in dry eye,nbsp;1.589nbsp;in normals; Plt;0.001). The contact rate for all full closures wasnbsp;6.4nbsp;times longer in dry-eye (0.045nbsp;versusnbsp;0.007, Plt;0.001)...
The increase in AV nodal conduction velocity can be observed as a decrease in the PR interval of the electrocardiogram. Sympathetic stimulation of His-Purkinje pathways speeds up ventricular depolarization. Sympathetic nerves exert their actions on the AV node and His-Purkinje fibers by releasing the...
A significant negative correlation between the ambient temperature and inter flash interval has been observed in specimens of Luciola cruciata at five different sites in central Japan5. For the Indian species Luciola praeusta at 20–40 °C, the pulse duration has been found to decrease ...
