Electrocardiogram in Pneumonia
The American Journal of Cardiology, 2012Findings on electrocardiogram may hint that pulmonary embolism (PE) is present when interpreted in the proper context and lead to definitive imaging tests. However, it would be useful to know if electrocardiographic (ECG) abnormalities also occur in patients with pneumonia and whether these are similar to ECG changes with PE.

Abstract Six-lead (3 standard, 3 augmented) electrocardiograms (ECGs) made on 500 conscious, untrained beagle dogs ranging in age from 4 months to 2 yr, were analysed. Measurements made on lead II produced the following range of values: Heart rate, 83–179 beats/min; P-R interval, 0.07–0.12 sec; QRS interval, 0.02–0.06 sec; Q-T interval, 0.15–0.21 sec;

The electrocardiogram in hyperparathyroidism∗
The American Journal of Cardiology, 1959Abstract The electrocardiographic changes in a case of hyperparathyroidism, before and after parathy-roidectomy, are illustrated and briefly discussed. The shortened Q-aT interval is confirmed as a readily measured index of shortened systole, characteristic of hypercalcemia.

A 56-year-old female was hospitalized and her admission ECG differed from previous tracings. Knowledge of variant cardiac anatomy along with awareness of common pitfalls in ECG recording reveals the clinical diagnosis and explains the difference.

To the Editor.— Did a recent case report inThe Journalreally support the author's appeal for "routine electrocardiography in all candidates for competitive athletics regardless of age?" (221:1047, 1972). A 20-year-old patient had well-documented, known congenital heart disease that she chose to conceal so she could do what she wanted.

The electrical activity generated during the cardiac cycle can be measured from the body surface as the ECG. This chapter will summarize the correlation between cardiac events and the ECG in the normal heart and will follow the time course of cardiac activation.
