RESUMEN
OBJECTIVE: To report a case of cardiac arrhythmia related to a low dose of endovenous lanatoside C. CASE REPORT: A 23-year-old pregnant woman with mitral regurgitation complicated with preeclampsia and pulmonary edema presented 2 episodes of atrial tachycardia induced by a intravenous digitalis (2 mg, IV and 1 mg, IV, respectively). CONCLUSION: This case calls attention to the need for further studies analysing the security of digoxin use in preeclampsia.

OBJECTIVE: To investigate the effectiveness and safety of various agents on paroxysmal atrial fibrillation in the elderly over 75 years old. METHODS: Totally 264 in-patients (75-91 years old, 185 males and 79 females) with atrial fibrillation history of less than 7 days were enrolled in this study. A total of 611 atrial fibrillation episodes were recorded, but 130 episodes (22.3%) of atrial fibrillation were auto-converted to sinus rhythm. The rest 481 episodes of atrial fibrillation were divided into six groups based on the drug used. RESULTS: The cardioversion ratio of atrial fibrillation were 9.5%, 46.9%, 71.7%, 55.9%, 32.7%, and 73.6% in control, cedilanid, amiodarone, propafenone, verapamil, and quinidine groups, respectively. Ventricular rate control were 5.4%, 83.6%, 84.9%, 77.9%, 78.8%, and 11.3% in those groups, respectively. The total effective rates of amiodarone and cedilanid groups were the highest. When the ventricular rate was controlled to below 90 bpm, the patients would almost complain of no discomfort. No severe side-effect was observed in each group. CONCLUSION: Amiodarone and cedilanid may be the proper drugs for the treatment of paroxysmal atrial fibrillation in the elderly. The above antiarrhythmics in each therapeutic group were relatively safe and effective.

For long time, there has been controversy on the use of digitalis in acute myocardial infarction (AMI). Hemodynamic studies before and after the use of cedilanid, simple QRS scoring, changes on the score of AMI and cardiac arrhythmia were analysed on 24 cases of AMI. Results of the pre- and post-medication values were improved as following: (1) Cardiac index (CI) were 2.34 +/- 0.2 and 3.21 +/- 0.26L/min/m2 two hours after medication (P < 0.05). (2) Left ventricular stroke work index (LVSWI) were 31.2 +/- 3.4 and 40.1 +/- 2.2 g-m/beat/m2 two hours after medication (P < 0.01). (3) Pulmonary capillary wedge pressure (PCWP) were 19.5 +/- 2.4 and 13.2 +/- 2.1 mmHg two hours after medication (P < 0.01). (4) Myocardial oxygen consumption triple index (TI) were 182000 +/- 14000 and 142000 +/- 12000 two hours after medication (P < 0.01). (5) There was no change or with only trivial aberration on systemic vascular resistance (SVR) and perfusion pressure of the coronary arteries (CCP). (6) Simple QRS scoring on electrocardiogram resulted that the size of infarcted areas were 4.02 +/- 0.3 points before and 3.01 +/- 0.23 points after the medication (P < 0.01), there was neither ventricular premature beats (VPB) nor increase of any other serious cardiac arrhythmias in the electrocardiogram care and record in 72 hours. From the hemodynamic studies, the beneficial effect of cedilanid is greater than its adverse effect. It is concluded that digitalis can be safely and effectively used in the treatment of AMI.

Nonocclusive intestinal ischemia is closely associated with heart disease and digitalization. Animal experiments and indirect evidence in man suggest that digitalis significantly decrease splanchnic blood flow. A case is described where peroperative intravenous digitalis caused profound intestinal ischemia. The report constitutes the first direct observation relating heart glycosides with intestinal ischemia in man.
