ECG Interpretation 4.1. A Systematic Method of Interpretation The routine use of a systematic method of interpretation for both normal and pathologic ECG patterns as outlined below, is an effective way to avoid errors by ensuring that all shown parameters are checked.

Ischemic Heart Disease (usually convex upwards, or straightened) To determine the ST elevation, it is important to know where to measure the ST segment from. For that, you need to find the J point. If you follow the QRS complex on your ECG, you will see that they are usually sharp-pointed. If you go down with the Q wave, up with the R wave, down the S wave and fo Ecg: You are reading off values from a computerized ECG reading.

The most important cause of ST segment abnormality (elevation or depression) is myocardial ischaemia or infarction. The ST segment is an interval between ventricular depolarization and ventricular repolarization. It is identified as the end of the QRS complex to the beginning of the T wave. The end of the T Mitral valve prolapse: the EKG is usually normal, but ST-segment depression and negative T waves may be seen in inferior leads. During or after a paroxysmal tachycardia: ST-segment depression and negative T waves may be seen, which in most cases disappears when the tachycardia ends. Due to repolarization abnormalities: Bundle branch blocks. Key aspects in the interpretation of the 12-lead ECG include the heart rate, the heart rhythm (both atrial and ventricular), the electrical axis (both the P-wave axis and the QRS axis), and knowledge of the normal intervals.

ST segment: isoelectric, slanting upwards to the T wave in the normal ECG; can be slightly elevated (up to 2.0 mm in some precordial leads) never normally depressed greater than 0.5 mm in any lead ; 5.

I detta kapitel presenteras den normala EKG-kurvan. Kunskap om den normala EKG-kurvan är en förutsättning för all EKG-diagnostik.
What is electrocardiography (ECG/EKG). ECG is a way to measure the electrical activity of the heart.

ST-sträckan och T-vågen förändras vid akut ischemi. ST-sträckan motsvarar kammarmyokardiets platåfas och sträcker sig från J punkten till T-vågen (Figur 1).Som framgår i Figur 1 är platåfasen långvarig vilket gör att merparten av kammarmyokardiet befinner sig i den ungefär samtidigt.I samma figur framgår också att membranpotentialen är relativt oförändrad under platåfasen. Upward sloping ST-depressions are normal at high heart rates. ST-elevations may occur in children, especially adolescents.

It starts at the J point (junction between the QRS complex and ST segment) and ends at the beginning of the T wave. The normal T wave is usually in the same direction as the QRS except in the right precordial leads. In the normal ECG the T wave is always upright in leads I, II, V3-6, and always inverted in lead aVR. Normal ST segment elevation: this occurs in leads with large S waves (e.g., V1-3), and the normal configuration is concave upward. At the heart of ECG interpretation lies the ability to determine whether the ECG waves and intervals are normal.
