The ST interval represents the period between the end of the QRS complex and the beginning of the T wave on an electrocardiogram (ECG). During this interval, the ventricles are in a state of plateau phase of the cardiac action potential, where the cells are depolarized and are preparing for repolarization. This phase corresponds to the time when the heart muscle is contracting and pumping blood. Abnormalities in the ST interval can indicate various cardiac conditions, such as ischemia or injury.
A prolonged PR interval, which indicates a delay in the electrical conduction from the atria to the ventricles, can be a sign of first-degree heart block. While it is often benign and may not require treatment, it can sometimes indicate underlying heart conditions that may be more serious. It's important for individuals with a prolonged PR interval to be evaluated by a healthcare professional to determine the cause and any necessary management. Regular monitoring may be recommended, especially if other symptoms or risk factors are present.
A prolonged PR interval is a condition observed on an electrocardiogram (ECG) where the time taken for electrical impulses to travel from the atria to the ventricles is longer than normal, typically exceeding 200 milliseconds. This can indicate a delay in the conduction through the atrioventricular (AV) node and may be associated with various heart conditions, such as AV block. While it can be benign in some cases, a prolonged PR interval may require further evaluation to determine its underlying cause and potential implications for heart function.
The vertical interval of a map, also known as the contour interval, is the difference in elevation between two adjacent contour lines. It represents the change in height over a specified horizontal distance and helps to indicate the steepness or flatness of the terrain. A smaller vertical interval indicates more frequent elevation changes, while a larger interval suggests more gradual changes. This measurement is crucial for understanding the topography of an area.

QRS-- A pattern seen in an electrocardiogram that indicates the pulses in a heart beat and their duration. Variations from a normal QRS pattern indicate heart disease.
The ECG of a patient with hypocalcemia will show q number of different distinct patterns. The ECG will show a T wave that is inverted and flattened, a prolongation of the QT interval, a narrowing of the QRS complex, a prolonged ST and ST depression, a reduction in the PR interval, and a prominent U wave.
the contraction of the ventricles
The R-R interval is a medical term used to describe the peak of one QRS to another. This is used to asses the ventricular rate.
In QRS wave, P wave shows atrial contraction or depolarisation whereas, T wave shows ventricular repolarisation.

An S-P interval is the time interval between the end of the QRS complex on an electrocardiogram (ECG) and the beginning of the T wave. It represents the time taken for the electrical impulse to travel from the ventricles through the AV node to the atria, allowing for ventricular filling before the next heartbeat. Changes in the S-P interval can indicate cardiac conduction abnormalities.
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

Some electrocardiographic (ECG) findings associated with hypokalemia include flattened or inverted T waves, a U wave, ST depression and a wide PR interval. Due to prolonged repolarization of ventricular Purkinje fibers, a prominent U wave occurs, that is frequently superimposed upon the T wave and therefore produces the appearance of a prolonged QT interval
