Mechanism Arises due to a combination of factors that are present in hospitalised patients with acute-on-chronic respiratory failure: Right atrial dilatation (from cor pulmonale) Increased sympathetic drive Hypoxia and hypercarbia Beta-agonists Theophylline [litfl.com]

In current practice, it was recommended in recent reports, to treat underlying illness and, when present, treat echocardiographically documented ventricular dysfunction with digoxin. [latunisiemedicale.com]

• Respiratory Distress

  CASE REPORT A previously well 12-day-old boy was admitted to the pediatric intensive care unit for severe respiratory distress. He was delivered at term with a birth weight of 3500 gram after an uneventful pregnancy with good Apgar scores. [latunisiemedicale.com]

• Tachycardia

  ECG Examples Example 1 Multifocal atrial tachycardia: Rapid irregular rhythm > 100 bpm. At least 3 distinctive P-wave morphologies (arrows). [litfl.com]

  As an emergent therapeutical approach we applied ice to the patient's face very briefly but no effect was observed on tachycardia. [latunisiemedicale.com]

• Heart Failure

  Most commonly seen in patients with severe COPD or congestive heart failure. It is typically a transitional rhythm between frequent premature atrial complexes (PACs) and atrial flutter / fibrillation. [litfl.com]

  Symptoms of congestive heart failure, such in our case, are rarely reported. [latunisiemedicale.com]

• Hypertension

  Four months later, he had a normal growth, no recurrence of symptomatic arrhythmia and the echocardiography showed a normal left ventricular function, a minor left-to-right shunting through the atrial defect without pulmonary hypertension. [latunisiemedicale.com]

• Heart Disease

  About 40% of patients with MAT have underlying structural heart diseases (SHDs), another 40% have no other conditions beside MAT, and the rest have a variety of other conditions such as respiratory illnesses (4). [latunisiemedicale.com]

• Right Axis Deviation

  Right axis deviation, dominant R wave in V1 and deep S wave in V6 suggest right ventricular hypertrophy due to cor pulmonale. [litfl.com]

• P Pulmonale

Asymptomatic patients are followed without pharmacologic treatment (4). [latunisiemedicale.com]

Tends to resolve following treatment of the underlying disorder. The development of MAT during an acute illness is a poor prognostic sign, associated with a 60% in-hospital mortality and mean survival of just over a year. [litfl.com]
