Baseline in an ECG refers to the flat line that represents the absence of electrical activity in the heart. It serves as a reference point for the peaks and valleys of the ECG waveform. Any deviation from the baseline may indicate abnormal electrical activity in the heart.
It means you are tachycardic or heart beating fast.

A PR segment represents the period of time in an electrocardiogram (ECG) between the end of the P wave and the beginning of the QRS complex. It reflects the conduction of electrical impulses through the atrioventricular (AV) node, allowing for a brief delay before the ventricles contract. The duration of the PR segment is crucial for assessing the heart's electrical conduction system and can indicate various cardiac conditions if prolonged or shortened.
Adrenaline increases heart rate and conduction velocity in the heart, which can lead to changes in the ECG. These changes may include a shortening of the PR interval, widening of the QRS complex, and an increase in heart rate.
In a normal ECG, the components measured along the isoelectric line include the baseline segment between heartbeats, specifically the PR segment and ST segment. The PR segment reflects the time taken for electrical impulses to travel from the atria to the ventricles, while the ST segment represents the period between ventricular depolarization and repolarization. Both segments are crucial for assessing the heart's electrical activity and can indicate various cardiac conditions when deviating from the isoelectric line.
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 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.
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.
A segment on an ECG tracing represents a specific period of electrical activity in the heart, typically reflecting the time between different phases of the heart's electrical cycle. For example, the PR segment indicates the time it takes for electrical impulses to travel from the atria to the ventricles, while the ST segment represents the period between ventricular depolarization and repolarization. Analyzing these segments helps diagnose various cardiac conditions and assess overall heart health.

A segment on an electrocardiograph (ECG) tracing represents a specific period of electrical activity in the heart. It typically refers to the flat portions between waves, such as the PR segment or ST segment, and indicates the time taken for electrical impulses to travel through the heart's conduction system. These segments are crucial for assessing the heart's electrical stability and diagnosing various cardiac conditions. Changes in segments can indicate issues like ischemia or arrhythmias.
