You are just having hypertonic contractions.
The sp interval is the time between the p wave arrival and the s wave arrival
The S-T interval represents the initial slow phase of ventricular repolarization. It is the time between completion of the QRS complex and beginning of the T-wave

The distance between a seismic station and the earthquake epicenter is determined from the S-P interval, which is the time difference between the time of arrival of the first P wave and the first S wave.

the time it takes for the secondary wave of an earthquake after the primary wave hits
The number of crests that pass a fixed point in a one-second time interval is called the "frequency" of the wave. It's also equal to the (speed of the wave) divided by the (wavelength)
The T wave represents the repolarization (or recovery) of the ventricles. The interval from the beginning of the QRS complex to the apex of the T wave is referred to as the absolute refractory period. The last half of the T wave is referred to as the relative refractory period (or vulnerable period). The T wave contains more information then the QT interval. The T wave can be described by its symmetry, skewness, slope of ascending and descending limbs, amplitude and subintervals like the TpeakTend interval. In most leads, the T wave is positive. However, a negative T wave is normal in lead aVR. Lead V1 may have a positive, negative, or biphasic T wave. In addition, it is not uncommon to have an isolated negative T wave in lead 3, aVL, or aVF.
The interval of time between successive occurrences of the same state in an oscillatory or cyclic phenomenon, such as a mechanical vibration, an alternating current, a variable star, or an electromagnetic wave.
This is called the "period".
PR (Pulse Rate) intervals are measured by using the gap between the beginning of the P wave (the excitation of the atria) and the beginning of the QRS , a typical deflection seen on an ECG (Electrocardiogram).
The wave's wavelength is the name is the distance between wave crest.
