In this video, I go through the P wave, QRS complex, T and U waves of the Electrocardiagram and go i Also known as an electrocardiogram or an EKG, an ECG is a test that detects and records the strength and timing of the electrical activity in your heart. This information is recorded on a graph that shows each phase of the electrical signal as it travels through your heart. The electrical signal begins in the sinoatrial node (1) which is located in ECG is a way to study the functioning of our heart, whether our heart is beating normally or it is altered we can study it on ECG graphs. In this article, we will try how to learn the step by step method to interpret the ECG graph. Normal corrected Q-c intervals are 0.44 seconds or less. There is no distinctly visible wave representing atrial repolarization in the ECG because it occurs during ventricular depolarization. Because the wave of atrial repolarization is relatively small in amplitude (i.e., has low voltage), it is masked by the much larger ventricular-generated QRS complex.

De letters ECG staan voor ElektroCardioGram. Het ECG is beter bekend als een hartfilmpje, hoewel het eigenlijk geen bewegend beeld toont. Electrocardiogram (ECG or EKG) is a non-invasive test that records and displays the electrical activities produced by heart muscle during a cardiac cycle. The ECG test is a standard clinical tool for diagnosing abnormal heart rhythms and to assess the general condition of a heart, such as myocardial infarctions, atrial enlargements, ventricular hypertrophies, and bundle branch blocks. Normal P wave is no more than 2.5 mm (two-and-a half1-mm-divisions) tall and less than 120 ms (three 1-mm-divisions) in width in any lead. In sinus rhythm when the SA node is the pacemaker, the mean direction of atrial depolarization (the P wave axis) points downward and to the left, in the general direction of lead II within a coordinate between 15 o and 75 o and away from lead aVR. With normal activation the electrical forces of the right ventricle are partially concealed by the larger sources arising from the activation of the left ventricle.

The ventricles then recover to their normal electrical EKG Abnormalities. I. Early elevation in V2-3 is generally seen in most normal ECG's; the ST elevation in V2- PQRST upside down in all leads except aVL.

Look for ST elevation, tall QRS voltage, "fishhook" deformity at the J point, and prominent T waves. ST segment elevation is maximal in leads with tallest R waves. LITFL Further Reading.

Because the wave of atrial repolarization is relatively small in amplitude (i.e., has low voltage), it is masked by the much larger ventricular-generated QRS complex. 2010-09-25 · with a good understanding of electrocardiograms (ECGs) , you’ll be able to diagnose a wide range of heart problems, an ECG waveform helps you in monitoring the patients condition and if necessary , begin lifesaving interventions ..

Note that the heart is beating in a regular sinus rhythm between 60 - 100 beats per minute (specifically 82 bpm).
