At the heart of ECG interpretation lies the ability to determine whether the ECG waves and intervals are normal. This chapter will focus on the ECG waves in terms of morphology (appearance), durations and intervals.
28 Φεβ 2011 · A simple, step-by-step guide to reading an ECG (also known as ECG interpretation), with included ECG examples and ECG quiz questions.
Assess P-wave morphology and PR interval. P-wave is always positive in lead II (actually always positive in leads II, III and aVF). P-wave duration should be <0,12 s (all leads). P-wave amplitude should be ≤2,5 mm (all leads). PR interval must be 0,12–0,22 s (all leads).
ECG Basics including Rate, Rhythm, Axis calculations and interpretation of P, Q, R, S, T U waves, segments and basic ECG calculations.
9 Αυγ 2024 · 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.
ECG interpretation starts with assessment of the P-wave and PR interval. The P-wave is generated by depolarization (activation, contraction) of the atria. The PR interval is the interval between the start of the P-wave and the start of the QRS complex.
Next we need to determine the AXIS of the EKG tracing. To do this we need to understand the basic 6 leads and their geometry. The EKG waveform comes from a measurement of surface voltages between 2 leads. A wave that is travelling towards the positive (+) lead will inscribe an upwards
