ECG changes from long-standing pulmonary disease were felt to "mask" ECG evidence of the large acute infarction that was evolving with the exception of the above noted subtle ST segment changes in the inferior leads and in lead V1. Pulmonary heart disease, also known as cor pulmonale, is the enlargement and failure of the right ventricle of the heart as a response to increased vascular resistance (such as from pulmonic stenosis) or high blood pressure in the lungs.. The patterns are usually printed on paper, giving doctors a hard copy to analyze. Sinus tachycardia is present in about 30 percent of PE cases. This loss of normal coordination between the two ventricles can reduce the efficiency of the heartbeat. The potential applications of fast rotation speed and dedicated cardiac reconstruction algorithms exploiting the multislice acquisition scheme of the data has opened new possibilities for thoracic imaging, starting with the possibility to integrate cardiac functional information into a diagnostic CT scan of the chest.
