| Abstrakt: | Background: Pulmonary embolism (PE) afflicts millions of individuals worldwide. Electrocardiography along with chest X-ray and arterial blood gas analysis represent the basic examinations to reinforce the clinical suspicion of PE. We describe the electrocardiographic (ECG) features in a series of patients with PE and a critical clinical presentation. Methods: We report the ECG findings registered at baseline, 48 hours after admission and on continuous ECG monitoring in 51 patients with PE and critical clinical conditions. Results: At admission, the following parameters were recorded: an S1Q3 pattern in 34 patients, a "septal embolic pattern" in 27, anterior lead T-wave inversion in 8, and a new right bundle branch block in 7. At 48 hours after admission a trend toward a regression of the S1Q3 and "septal embolic" patterns was noted together with evident T-wave inversion in the anterior leads. During continuous ECG monitoring no major arrhythmias were recorded, even in case of cardiopulmonary arrest. Conclusions: Critical PE induces transient ECG abnormalities reflecting right ventricular overload and/or strain. The patient's clinical status is usually not complicated by major ventricular arrhythmias, not even in case of cardiopulmonary arrest. |
