this record where there are Q waves in infe-rior leads in a young man with no history of infarction. Where an inferior inf arct has healed the T wave, abnormalities in II, III and AVF may have disappeared. The only rem-nants of the event are abnormal Q waves in leads III and AVF. In this tracing, the Q waves do not meet the criteria for ...

inferior MI will face post MI complications like heart block, which will change their otherwise better prognosis1–3. Traditionally the inferior MI was defined as follow: Q waves with duration of 40 msec or more and Q/R ratio of 0.25 or more in leads II, III or aVF4. Several studies suggest that when Q waves

Patients with abnormal Q waves had a higher initial heart rate, were more likely to have an anterior infarction, had greater ST segment elevation, less ST segment depression and a higher predicted infarct size according to Aldrich score. Abnormal Q waves on initial ECG. Table 3 shows the proportion of patients with abnormal Q waves by time from symptom onset to initial ECG. Over half (53%) of ...

interesting findings. Q waves usually represent scar tissue, yet there are numerous causes for the develop-ment of abnormal Q waves that are not due to myocardial infarction.1 Limited information is available to explain readily the transient nature of Q waves induced by exercise. We pre-sent an ECG illustrating a less appreciated cause of Q wave.
