Reversible electrocardiographic changes in severe acute asthma

D Siegler


Previous reports have documented the occurrence of reversible electrocardiographic changes including right axis deviation, P pulmonale, right bundle-branch block, and ST-segment and T-wave abnormalities in patients with acute attacks of asthma. In a further systematic study, the electrocardiographs of 63 patients admitted with severe acute asthma have been evaluated. The most consistent change was an abnormally vertical P-wave axis in 78% of the patients. P pulmonale was present in 22% and right ventricular enlargement in only one patient. Right axis deviation, right bundle-branch block, and rhythm abnormality were not present in any patient. In 11%, ST-segment or T-wave abnormalities suggesting myocardial ischaemia were noted. These abnormalities persisted for up to nine days and were unexplained. Other ECG abnormalities in acute asthma may reflec positional changes of the heart due to overdistension of the lungs. All ECG changes resolved after clinical improvement.

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
