A hemodynamic complication of verapamil therapy in a neonate.

The effectiveness and lack of undesirable side-effects has made Verapamil the drug of choice in the treatment of paroxysmal supraventricular tachycardia in infants without underlying heart disease. The case described demonstrates the occasional severe negative inotropic effect of the drug, independent of its influence on heart rate and conduction. Severe heart failure and shock ensued after a therapeutic dose of i.v. Verapamil in a newborn suffering from atrial flutter with no associated heart disease. Although the arrhythmia was promptly converted to sinus rhythm, the baby required two hours of cardiopulmonary resuscitation and inotropic support. Follow-up during the first year of life revealed a normal healthy baby. Attention to the hemodynamic status in addition to continuous ECG monitoring is mandatory during i.v. Verapamil administration also in patients without underlying heart disease.

Influence of varying inspired oxygen tensions on the pulmonary venous admixture (shunt) of mechanically ventilated patients.

Pulmonary venous admixture (shunt) was measured in 10 mechanically ventilated patients with respiratory failure at varying oxygen tensions. All patients manifested a drop in pulmonary shunt as FIO2 was increased from 0.21 to 0.4. Further increase in FIO2 led to a gradual increase in the calculated venous admixture. The clinical significance of the conventional measurements of pulmonary shunt at FIO2 = 1.0 is questionable because of the marked effect of FIO2 on pulmonary shunt. Consequently, shunt measurements should be performed with the clinically useful FIO2.

Continuous electrocardiographic monitoring with Holter electrocardiocorder throughout all stages of gastroscopy.

Continuous electrocardiographic recording on magnetic tape with a Holter electrocardiocorder was performed during gastroscopy on 55 consecutive patients. ECG recording was begun before premedication and was terminated 1 hr after the withdrawal of the gastroscope. The ECG changes during the different stages of the procedure were separately analyzed: 38.18% of patients had E.C.G. changes--sinus tachycardia (20%), ST-T changes (23.6%), ventricular and atrial premature beats (20.0% and 7.27%, respectively). atrial premature beats with aberrant conduction (3.6%), and coronary sinus rhythm (1.8%). All changes disappeared spontaneously after the procedure. Although relatively safe, gastroscopy requires careful consideration of the risks, especially in severe cardiac patients.
