Electrocardiogram (ECG): Definition, Meaning, Types, …

Electrocardiogram (ECG) is defined as a recording of the heart's electrical activity. It is simple test, a graphic record produced by an electrocardiograph provides details about one's heart rate and rhythm and depicts if the heart has enlarged due to hypertension or evidence of myocardial infarction (if any). Q2.

Electrocardiogram (ECG)

An ECG (electrocardiogram) is done by a specially trained healthcare professional at a hospital, clinic or GP surgery. There are 3 different ways an ECG may be done: while resting. over a period of time, while wearing a portable ECG. while doing exercise or after being given medicine that changes your heart rate (stress test)

Reference (normal) values for ECG (electrocardiography)

Common findings. Sinus rhythm (which is the normal rhythm) has the following characteristics: (1) heart rate 50–100 beats per minute; (2) P-wave precedes every QRS complex; (3) the P-wave is positive in lead II and (4) the PR interval is constant. Causes of bradycardia: sinus bradycardia, sinoatrial block, sinoatrial arrest/inhibition, second ...

ECG Library Homepage. ECG Diagnostic criteria. There are numerous voltage criteria for diagnosing LVH, summarised below. The most commonly used are the Sokolov-Lyon criteria: S wave depth in V1 + tallest R wave height in V5-V6 > 35 mm. Voltage criteria must be accompanied by non-voltage criteria to be considered diagnostic of LVH.

Bradycardia: < 50 bpm. Normal Heart Rates in Children. Newborn: 110 – 150 bpm. 2 years: 85 – 125 bpm. 4 years: 75 – 115 bpm. 6 years+: 60 – 100 bpm. Other paper speeds: 50mm/sec. Doubling the standard rate will cause the ECG to appear drawn out or wider complex than 25mm/sec paper speeds.

Myocarditis ECG changes • LITFL • ECG Library Diagnosis

The most common ECG abnormalities seen in myocarditis are: Sinus tachycardia. Non-specific ST segment and T waves changes. Other ECG changes are variable, and may include: Prolonged QRS. QT prolongation. Diffuse T wave inversion. Ventricular arrhythmias. AV conduction defects.

The ECG leads: Electrodes, limb leads, chest (precordial

The ECG leads. Before discussing the ECG leads and various lead systems, we need to clarify the difference between ECG leads and ECG electrodes.An electrode is a conductive pad that is attached to the skin and enables the recording of electrical currents. An ECG lead is a graphical description of the electrical activity of the heart and it is created by …

Large Block Method to Calculate Heart Rate

3 large blocks: 100. 2 large blocks: 150. 1 large block: 300. We know the "normal" heart rate is 60-100 (although some would argue that 50-90 is more accurate). Using 60-100 the normal heart rate should have 3-5 large blocks between R-waves. More than 5 large blocks is a bradycardia and fewer than 3 blocks is a tachycardia.

In brief: What is an electrocardiogram (ECG)?

An ECG is used to check how the heart is functioning. It mainly records how often the heart beats (heart rate) and how regularly it beats ( heart rhythm ). It can give us important information, for instance about possible narrowing of the coronary arteries, a heart attack or an irregular heartbeat like atrial fibrillation.
