[Extrasystole in the neonatal period].

We investigated the clinical course in 35 healthy newborn with premature beats and studied the literature with regard to their frequency, pathogenesis, and therapy with the following results: Investigations with continuous monitoring or long-term ECG registration show a frequency of 7-25%. In literature, almost one-fourth, in our patients one-half of the newborn have ventricular premature beats. These will probably disappear later than atrial premature beats, but their prognosis is not worse. The premature beats of newborn are often complex (blocked or aberrant conduction, bigeminus, tachycardia). Atrial flutter is sometimes associated. In one-half of cases they disappear spontaneously during the first month of life. However, they lasted for longer than 4 months in 7 out of 35 infants. The disorder increased after birth in 2 children, which is unusual. Therapy was indicated if there were signs of heart failure, frequent or increasing rate of tachycardia or atrial flutter. Premature beats do not indicate primary operative delivery. Immaturity of the central and autonomous nervous system and of the conduction-tissue of the heart may be the reason for frequent perinatal premature beats.

[Fetal supraventricular extrasystole: indication for fetal echocardiography?].

The purpose of this study was to assess the incidence of congenital heart disease (CHD) in fetuses with premature atrial contractions (PAC) and to check whether these fetuses should be referred for a special fetal echocardiogram. Out of 120 fetuses with PACs and 75 fetuses with CHD both conditions were present in only 9 fetuses (= 7.5%). Two pregnancies were terminated because of associated severe fetal anomalies. After birth PACs disappeared in all other cases spontaneously. Despite higher numbers, the incidence of fetal CHD was not statistically significant higher in fetuses with PACs. Thus, recognition of fetal PACs should lead to a referral for a special fetal echocardiographic examination.

[Extrasystoles during extracorporeal biliary shockwave lithotripsy. Their incidence and clinical significance].

Incidence and clinical significance of cardiac side effects of extracorporeal shock-wave lithotripsy (ESWL) were prospectively analysed for 85 patients (26 men, 59 women; mean age 44 [17-81] years) with cholecystolithiasis (n = 70) or choledocholithiasis (n = 15). 24-hour ECG monitoring was undertaken on the day of treatment. Additionally, during ESWL cardiac rhythm and blood pressure were monitored. ESWL was performed with an electromagnetic lithotriptor under light anaesthesia with intravenous diazepam (10 mg) and pethidine (75-100 mg). There were no superventricular premature systoles in any of the patients during treatment. In 15 patients with occasional ventricular premature systoles (VPS) (6-81 per 23 hours) in the 24-hour ECG the number of VPS increased during the one-hour ESWL procedure significantly to 6-55 (P less than 0.05). 14 of these patients had an unremarkable cardiac history. Changing the lithotriptor coupling angle failed to suppress the VPS in only two patients. In these two it was necessary to trigger the shock wave with the ECG. Blood pressure rose markedly (up to 220 mm Hg systolic) during ESWL in only three patients, known hypertensives. But this rise was easily controlled with nifedipine, 10 mg sublingually. These data demonstrate that ESWL is a safe alternative to operative treatment, even in the presence of existing cardiac disease. Nonetheless, precautions should be taken in case there are complications.

Clinical evaluation of bisoprolol in the treatment of extrasystoles and sinus tachycardia: an interim report.

The effectiveness and safety of bisoprolol, a newly developed beta-adrenergic blocking drug, in the treatment of arrhythmias were evaluated in 17 patients with premature ventricular contraction (PVC), 8 with premature atrial contraction (PAC) and 7 with sinus tachycardia. More than 50% reduction of the PVC frequency was observed in 7 out of 16 patients. PVC was reduced in 2 out of 5 patients at a daily dose of 2.5 mg. The PAC frequency was decreased in 50% of the patients, and sinus tachycardia was improved in all 7 patients. Adverse reactions were observed in 8 of 32 patients. This preliminary study suggests that the antiarrhythmic effects of bisoprolol could be assessed starting at a daily dose of 2.5 mg to determine its optimal effective dose in Japanese patients.

Extrasystoles: side effect of kangaroo care?

OBJECTIVE: To present an unpublished reason for an arrhythmic electrocardiogram (ECG) recording during kangaroo care in a preterm infant. DESIGN: Case report. PATIENT: Preterm infant. MEASUREMENTS AND MAIN RESULTS: A preterm infant exhibited cardiac arrhythmia on the ECG monitor during kangaroo care, leading to interruption of kangarooing. Arrhythmia disappeared after placing the baby back into the incubator. The most likely reasons for arrhythmia were excluded. However, arrhythmia reappeared upon continuation of kangaroo care. ECG monitoring revealed the reason for the monitoring error. CONCLUSIONS: ECG monitoring during kangaroo care should cause error because of superimposed electric activity from the parent. Oxygen saturation represents a more reliable method of monitoring during kangaroo care.

Ventricular extrasystoles and intracellular electrolytes in hypokalemic patients before and after correction of the hypokalemia.

Fifty-four initially hypokalemic patients, 43 of whom were on diuretic treatment, were given potassium supplementation until they showed a repeatedly normal serum potassium level. Muscle specimens obtained by percutaneous biopsy revealed that there were no concomitant increases in muscle potassium content, nor in intracellular potassium concentration, except in the very small group (6 patients) with a muscle magnesium content of greater than or equal to 3.95 mmol/100 g fat free dry solids (FFDS) and an initially lower muscle potassium content (less than or equal to 39.9 mmol/100 g FFDS). ECG, registered for 3 hours on a portable ECG tape recorder before and after correction of the serum potassium level, showed no change in the frequency of ventricular ectopic beats.

An evaluation of a new ECG monitor which detects and classifies ventricular extrasystoles.

A device is described which is highly efficient in detecting and classifying ventricular ectopic beats. This instrument may have a significant role in patient monitoring. The system is based on analysis of a 5 electrode orthogonal system with comparison of QRS wave forms with a stored normal wave form. The design was based on a test derived from 26 patients and evaluated further on long recordings of 16 other patients. Results indicate that the device is highly reliable in QRS detection and in detection of ventricular ectopic beats. The problem of artefacts due mainly to patient movement is held within resonable limits.
