Self-administered hyperventilation cardiopulmonary resuscitation for 100 s of cardiac arrest during Holter monitoring.

An 80-year-old man remained conscious due to vigorous deep breathing during 100 s of ventricular arrest which was recorded on a Holter ECG. Arterial blood flow is considered to have been maintained by changes in intrathoracic pressure produced by deep respiratory movements. This case may represent a pure model of the "thoracic pump" mechanism.

Dilated cardiomyopathy complicated by a pedunculated and mobile left ventricular thrombus on ruptured false tendons.

A 68-year-old man was admitted with congestive heart failure. He was treated with diuretics and digitalis; thereafter, the two-dimensional echocardiogram suggested a pedunculated and mobile left ventricular thrombus. He underwent surgical thrombectomy because of the high risk of systemic embolization.

[Tetralogy of Fallot revealed by autopsy in an elderly subject].

A 62-year-old women had a history of cyanosis and easy fatigability from school age but had refused medical examinations. She was admitted to our department with exacerbation of dyspnea at the age of 59. Laboratory tests showed hypoxia complicated with polycythemia with 35 mmHg of PaO2, 8.
