The value of electrocardiography in prognosticating clinical deterioration and mortality in acute pulmonary embolism: A systematic review and meta-analysis. One of the most useful and commonly used diagnostic tools is electrocardiography (EKG) which measures the heart's electrical activity as waveforms. ECG interpretation traditionally starts with an assessment of the P-wave. They specialize in Cardiology, has 18 years of experience. This is because the electrocardiogram represents a balance of electrical forces between the left and right ventricles at any given instant in time. Is Right bundle branch block considered heart disease? One of the main challenges in diagnosing a PE is that its symptoms, such as chest pain, shortness of breath, and lightheadedness, are common in several other cardiovascular conditions. The condition is a medical emergency, the complications of which include pulmonary edema, shock, and death. It is fundamental to compare the current ECG with previous recordings. publications. Pulmonary embolism Pulmonary Embolism (PE) Pulmonary embolism (PE) is the occlusion of pulmonary arteries by thrombi that originate elsewhere, typically in the large veins of the legs or pelvis.

Body mass index (BMI) was measured, and pulmonary function tests, ECG, echocardiography and right heart catheterisation (only patients) were performed. Based on the low voltage in leads V1, V2, V3, the rightward frontal plane axis, incomplete right bundle-branch block (RBBB), and persistent precordial S waves, the computer interpreted the overall pattern as consistent with pulmonary disease.
