ECG of a 75-year-old man presenting with central chest pain.
In complete heart block, all atrial impulses are blocked at the atrioventricular (AV) node. Ventricular depolarisation may be maintained by an escape pacemaker. Nodal escape rhythms, originating above...
There are however are a number of abnormalities with this 12-lead ECG:.
This ECG shows the patient to be in atrial flutter with a variable ventricular response and left bundle branch block configuration. His high sensitivity troponin was moderately elevated..
There is ST segment elevation of approximately 5mm across his chest leads V1–V5. There is no T wave inversion or pathological Q waves. This suggests a hyperacute anterior septal ST elevation...
There is ST segment elevation of up to 15 mm in V1–V6 suggestive of an extensive anterior lateral ST elevation myocardial infarction. There is ST segment depression in the inferior leads II, III and...
There is ST segment elevation across a number of leads. However, in this case the changes are not as a consequence of acute myocardial infarction. Rather, this ECG suggests early repolarisation...
A 12-lead ECG was recorded (Figure 1)..
Ectopic beats or extrasystoles are extra beats that come early in the cardiac cycle. They were first described by the Chinese physician, Pien Ts'lo, in 600 BC. Ectopic activity is detected in 40–75%...
The most striking abnormality is the prolonged QRS duration. The QRS duration should be up to 100 milliseconds; whereas in this example, it is considerably prolonged, resulting in a wide QRS complex....
