EKG Interpretation & Heart Arrhythmias Cheat Sheet

Use this EKG interpretation cheat sheet that summarizes all heart arrhythmias in an easy-to-understand fashion. One of the most useful and commonly used diagnostic tools is electrocardiography (EKG) which measures the heart's electrical activity as waveforms. An EKG uses electrodes attached to the skin to detect electric currents moving through the …

Normal paediatric ECG • LITFL • ECG Library Diagnosis

Pathophysiology. At birth, the right ventricle is larger and thicker than the left ventricle, reflecting greater physiological stresses placed upon it in utero (i.e. pumping blood through the relatively high-resistance pulmonary circulation).. This produces an ECG picture reflecting that of a right ventricular strain pattern in adults:. T-wave inversions in V1-3

ECG Axis Interpretation • LITFL • ECG Library Basics

Method 2: Three Lead analysis – (Lead I, Lead II and aVF) Next we add in Lead II to the analysis of Lead I and aVF . A positive QRS in Lead I puts the axis in roughly the same direction as lead I.; A positive QRS in Lead II similarly aligns the axis with lead II.; We can then combine both coloured areas and the area of overlap determines the axis.

Electrocardiogram (ECG or EKG)

An ECG can diagnose a current or previous heart attack. The patterns on the ECG results can help a healthcare professional learn which part of the heart is damaged. Blood and oxygen supply to the heart. An ECG done while you're having chest pain symptoms can help your care team learn whether reduced blood flow to the heart is the cause.

Brugada syndrome: ECG, clinical features and management

Most patients have normal ECG during the majority of the time but they convert to the Brugada ECG patterns spontaneously. As noted above, certain drugs () and situations (sleeping, rest, fever) may also induce ECG changes. The patient may display all three types of Brugada ECG, even during the same …
