7 ECG Waves and Segments

8 ECG Waves and Segments

9 ECG Waves and Segments Bazett's formula: QT corrected = QT measured SQRT (RR interval)

10 12-lead ECG

11 12-lead ECG

12 Normal ECG

13 Where ECG leads look at? Lateral Anterior/ Septal Anterior Inferior Lateral Anterior/ Septal Lateral Inferior Inferior Anterior Lateral

14 ECG Analysis Step 1: Is the Rhythm Regular or Irregular? Step 2: Are All QRS Complexes Similar and Narrow, and is ST segment is isoelectric? Step 3: Are All P Waves Similar and Are PR Intervals Normal? Step 4: Is the Rate Normal? Step 5: Do Waves and Complexes Proceed in Normal Sequence?

15 Systematic ECG Analysis 1. Check the patient details - is the ECG correctly labelled? 2. What is the rate? 3. Is this sinus rhythm? If not, what is going on? 4. What is the mean frontal plane QRS axis? 5. Are the P waves normal (Good places to look are II and V1)? 6. What is the PR interval? 7. Are the QRS complexes normal? 8. Are the ST segments normal, depressed or elevated? 9. Are the T waves normal? 10. What is the QT interval? 11. Are there abnormal U waves?

16 Systematic ECG Analysis: Heart Rate Estimation

17 Systematic ECG Analysis: Cardiac Axis

18 Systematic ECG Analysis: Cardiac Axis Three Easy steps 1- Estimate the overall deflection (positive or negative, and how much) of the QRS in standard lead I. 2- Do the same for avf. 3- Plot the vector on a system of axes, and estimate the angle. Normal QRS axis Normal axis = -30 to +120 degrees Left axis deviation is left of -30 degrees Right axis deviation is right of +120 degrees Axis is abnormal Lead II is more negative than positive. Lead III is more positive than lead II.

54 Pacemaker/Conduction Abnormalities Accessory Pathway or Wolf Parkinson White (WPW) Syndrome Abnormal, congenital extra pathways between the atria and ventricles or/and conduction tissue, and can perforate the electrically insulating fibrous ring that normally separates the atrial and the ventricular chambers. Atrio-Ventricular conduction could be achieved bypassing the AV node. This means that fast Atrial rates (i.e. AF) could be conducted to ventricles at high rates causing serious tachycardia.

55 Pacemaker/Conduction Abnormalities WPW Syndrome The WPW syndrome is a combination of the pre-excitation pattern, and tachycardia. The tachycardia may be due to impulse conduction down via the AV node and back up the accessory pathway (commonest, called orthodromic tachycardia) The other way around (down accessory pathway, up AV node, termed antidromic tachycardia) WPW Syndrome = short PR interval + Delta wave + Wide QRS complex + Tachycardia Pre-exited ECG = short PR interval + Delta wave + Wide QRS complex

77 III- Conduction Abnormalities The Long QT Syndrome Normally, the QT-interval is less than 50% of the preceding RR-interval. The long QT-interval symbolises a long ventricular systole. The ST-interval is simultaneous with the phase 2 plateau of the ventricular membrane action potential. The slow Ca2+ -Na+ - channels remain open for more than 300 ms as normally. The net influx of Ca2+ and Na+ is almost balanced by a net outflux of K+. Hereby, a long phase 2 plateau or isoelectric segment is formed. Long QT syndrome one of the common causes of unexplained sudden cardiac death (especially in young people) due to occurrence of fatal arrhythmia called (Torsades de pointes, i.e. polymorphic VT).
