    摘要： A method and apparatus for treatment of hypertension and heart failure by increasing vagal tone and secretion of endogenous atrial hormones by excitory pacing of the heart atria. Atrial pacing is done during the ventricular refractory period resulting in atrial contraction against closed AV valves, and atrial contraction rate that is higher than the ventricular contraction rate. Pacing results in the increased atrial wall stress. An implantable device is used to monitor ECG and pace the atria in a nonphysiologic manner.

    摘要： A method and apparatus for treatment of hypertension and heart failure by increasing secretion of endogenous atrial hormones by pacing of the heart atria. Atrial pacing is done during the ventricular refractory period resulting in premature atrial contraction that does not result in ventricular contraction. Pacing results in the atrial wall stress, peripheral vasodilation, ANP secretion. Concomitant reduction of the heart rate is monitored and controlled as needed with backup pacing.

    摘要： A method for accessing a pericardial space of a heart of a mammalian patient is disclosed comprising: guiding a catheter through a coronary sinus of the heart and to a cardiac vein; advancing said catheter to a distal segment of the cardiac vein; intentionally puncturing the vein with the catheter to access the pericardial space, and performing a therapy or a diagnostic procedure using the catheter an the puncture in the vein and using the pericardial space.
