There is no difference between an ECG and an EKG. Both refer to the same procedure, however one is in English (electrocardiogram – ECG) and the other is based on the German spelling (elektrokardiogramm – EKG).

Electrocardiogram. An electrocardiogram (ECG or EKG) records the electrical signal from your heart to check for different heart conditions.

The major difference between CPR and an AED is that CPR has very, very little chance of bringing someone back to life after cardiac arrest, while an AED has the potential to restart their heart and brain functions. ... CPR and an AED are not the same thing but go hand- in- hand when saving someone's life.

2 – Relationship between the Cardiac Cycle and ECG: Initially, both the atria and ventricles are relaxed (diastole). The P wave represents depolarization of the atria and is followed by atrial contraction (systole). Atrial systole extends until the QRS complex, at which point, the atria relax.

Question: Unlike the discrete waveform from an ECG, the EMG waveform is irregular. ... Answer: An ECG records electrical activity from the heart. Unlike the heart, skeletal muscle does not contract in a fully synchronized fashion. Instead, an EMG records the unsynchronized electrical activity of many muscle fibers.

Introduction. The T wave is the most labile wave in the ECG. T wave changes including low-amplitude T waves and abnormally inverted T waves may be the result of many cardiac and non-cardiac conditions. The normal T wave is usually in the same direction as the QRS except in the right precordial leads (see V2 below).

The Standard 12 Lead ECG. The standard 12-lead electrocardiogram is a representation of the heart's electrical activity recorded from electrodes on the body surface. This section describes the basic components of the ECG and the lead system used to record the ECG tracings.

Electrocardiogram (ECG/EKG) Often done alongside an echocardiogram, the electrocardiogram is also a painless, non-invasive test that can help to diagnose mitral valve prolapse. During this test, the patient lies down and electrode discs are placed on the chest, arms, and legs.

While both EKGs and telemetry monitor a patient's unique electrocardiogram for a period long enough to obtain information, the two pursuits aren't identical. Whereas telemetry is a relatively general form of monitoring, EKG technicians perform a more specific type of monitoring.

An ECG Can Recognize the Signs of Blocked Arteries. Unfortunately, the accuracy of diagnosing blocked arteries further from the heart when using an ECG decrease, so your cardiologist may recommend an ultrasound, which is a non-invasive test, like a carotid ultrasound, to check for blockages in the extremities or neck.

Difference Between Heart Rate and Pulse. Heart rate is the number of times per minute that the heart contracts - the number of heart beats per minute (bpm). ... Pulse is the mechanical pulse of blood flow through the capillaries caused by the contractions of the heart per minute.

An ECG may reveal abnormalities in heart rhythm, damage from a previous heart attack, or an enlarged heart. If fatty deposits have narrowed one or more of your coronary arteries enough to interfere with the flow of blood to the heart, an ECG can detect that.

ECG records the electrical activity generated by heart muscle depolarizations, which propagate in pulsating electrical waves towards the skin. Although the electricity amount is in fact very small, it can be picked up reliably with ECG electrodes attached to the skin (in microvolts, or uV).

Difference Between Heart Rate and Pulse. Heart rate is the number of times per minute that the heart contracts - the number of heart beats per minute (bpm). Heart rate is most accurately measured from the thorax with the transmitter of heart rate monitor or the electrodes of the electrocardiograph (EKG).

An ECG can help your doctor detect problems in your heartbeat and heart structure that could cause palpitations. The test will be done either while you rest or during exercise (stress electrocardiogram).

An ECG can show evidence of a previous heart attack or one that's in progress. The patterns on the ECG may indicate which part of your heart has been damaged, as well as the extent of the damage. Inadequate blood and oxygen supply to the heart.
