[The dynamics of the heart contraction rate and arterial pressure during physical loading after a heart transplant].

Compared to healthy controls, patients with transplanted heart have higher baseline heart rate (HR), delayed initial HR reaction, slower changes of HR both during exercise and after it, diminished chronotropic and inotropic reserves. The data obtained contribute to better understanding of physiology of transplanted denervated heart and objective assessment of patients after heart transplantation.

[Arrhythmia in patients after heart transplantation].

Holter monitoring was performed in 15 patients surviving over 3 months after homotopic cardiac transplantation. The frequency and types of arrhythmias occurring in the grafted innervated heart were studied according to its postoperative period duration. The follow-up lasted 3 to 29 months.
