Precise Determination of Electrode Positions C1-C6 Accurate positioning of the pre-cordial leads is critical for accurate diagnostic evaluation of the ECG. Deviations of just a few centimetres on the surface of the thorax result in significant changes in the ECG waveform. Therefore the so-called “Angle of Louis“ can be used to determine electrode positions C1 –C6 accurately (1) Use the middle finger of the right hand to palpate the first intercostal space at the left sternal border. (2) Count while successively palpating the subsequent intercostal spaces up to the 4th intercostal space. (3) Place the C2 electrode on the left sternal border of the 4t intercostal space. (4) Place the C1 electroce on the right sternal border or the 4th intercostal space. (5) Place electrodes C5 and C6 as shwon in the illustration using visual judgement. Record a 12-lead ECG strip for a period of 10 seconds, if possible, with an additional rhythm strip. If the quality of the ECGrecording is insufficient, check the condition of the system and the subject (see Technical problems, suboptimal recording quality section) and, after optimizing the conditions, record the ECG again. If the quality of the recording is still poor, inform the study doctor.

Begins where P leaves the isoelectric line. Ends at the beginning of the Q wave. If there is no Q wave present, the measurement ends at the beginning of the R wave upstroke. Measured in Lead II, otherweise in the lead with the best representation.

Begins where Q leaces the isoelectric line. Ends where T meets the isoelectric line. Measured in Lead II, otherweise in the lead with the best representation. The QT time is the measured, not the corrected, QT time.

1st degree: PQ interval > 0,20 seconds 2nd degree: Includes Type 1 (Wenckebach) and Type 2 (Mobitz) Typ I, Wenckebach: in each cycle the PR interval is prlongued until a QRS complex is blocked. Typ II, Mobitz: intermittent blocking of a QRS complex with no prior increase in the PR interval. 3rd degree: P waves appear independent of the QRS complexes, mostly with a higher frequency than the ventricular escape rhythm.

Left anteriorer hemiblock: extreme left axis deviation in the pre-cordial leads, deep S wave in V5-V6, QRS is not widened. Left posteriorer hemiblock: right to extreme right axis deviation. In cases of atrial fibrillation or irregular rhythm on the ECG,the intervals are measured three times in total, each time during a different cycle. The mean value is entered.
