This study evaluates safety and efficacy of low-voltage direct-current (DC) electrical stimulation of angiogenesis in rabbits with myocardial infarction (MI). Thirty Japanese rabbits were divided into treatment and control groups, and MI was induced by ligation of the left circumflex (LCX) artery. Two platinum electrodes were placed directly on the epicardium on either side of LCX artery. Low-voltage DC stimulation (4.0 V/cm, 30 min/day) was performed in the treatment group immediately after surgery until fourth week post-operatively. Cardio-electrophysiological, respiratory, hematological, blood biochemical, histopathological, immunohistochemical parameters, as well as capillary density at the marginal zone of myocardial infarct were compared between treatment and control groups. Capillary density in the treatment group (63.1 +/- 2.2) was significantly higher (P < 0.01) than that in controls (45.4 +/- 3.9). Overall mortality was 6.7%, and the prevalences of pneumothorax and intraoperative arrhythmia were 3.3 and 6.7%, respectively. Transient hypotension, anemia, leukocytosis, hypoxemia, and a slight increase in myocardial enzymes levels were observed in both groups. Regarding electrical stimulation, no adverse reactions except a minor infiltration of inflammatory cells and mild degeneration were observed in the myocardium. It was, therefore, concluded that low-voltage DC stimulation in the MI rabbits was not only safe but also effective in promoting angiogenesis in the myocardium.

Application of electric current in treatment without the generation of perceptible heat. It includes electric stimulation of nerves or muscles, passage of current into the body, or use of interrupted current of low intensity to raise the threshold of the skin to pain.
An electrophysiologic technique for studying cells, cell membranes, and occasionally isolated organelles. All patch-clamp methods rely on a very high-resistance seal between a micropipette and a membrane; the seal is usually attained by gentle suction. The four most common variants include on-cell patch, inside-out patch, outside-out patch, and whole-cell clamp. Patch-clamp methods are commonly used to voltage clamp, that is control the voltage across the membrane and measure current flow, but current-clamp methods, in which the current is controlled and the voltage is measured, are also used.
Removal of tissue with electrical current delivered via electrodes positioned at the distal end of a catheter. Energy sources are commonly direct current (DC-shock) or alternating current at radiofrequencies (usually 750 kHz). The technique is used most often to ablate the AV junction and/or accessory pathways in order to interrupt AV conduction and produce AV block in the treatment of various tachyarrhythmias.
The species Oryctolagus cuniculus, in the family Leporidae, order LAGOMORPHA. Rabbits are born in burrows, furless, and with eyes and ears closed. In contrast with HARES, rabbits have 22 chromosome pairs.
An electrochemical technique for measuring the current that flows in solution as a function of an applied voltage. The observed polarographic wave, resulting from the electrochemical response, depends on the way voltage is applied (linear sweep or differential pulse) and the type of electrode used. Usually a mercury drop electrode is used.
