WebAug 28, 2024 · However, ECT is not the only treatment that can lead to ECG abnormalities. A dose of >400 mg/day of Flecainide (Tambocor) has been known to cause arrhythmias and T-wave inversions as well. Even illicit drugs, such as cocaine use has been found to cause transient negative T-waves in emergency departments. Figure 8: Post ECT. WebThe following ECG criteria are commonly used to diagnose LBBB: QRS duration ≥0,12 seconds. Leads V1-V2: deep and broad S-wave. The small r-wave is missing or smaller than normal. If it is missing, a QS complex appears in V1 and occasionally V2, but rarely V3. The S-wave in V1 may be notched and resemble the letter “W”.
WebNov 26, 2024 · The T wave morphology is identical to patients who reperfuse after a successful PCI. · If the artery remains open, the T waves evolve over time from biphasic to deeply inverted. · The coronary perfusion is unstable, however, and the LAD can re-occlude at any time.
