Transient atrial flutter in premature infants.
A preterm newborn of 34 weeks gestational age and birth weight of 1900 g was referred for a cardiology evaluation due to having a tendency to tachycardia since birth (heart rate approximately 160 beats/min) without tachycardic stimulants. From his sixth day of life, he frequently experienced a heart rate over 190 beats/min with no haemodynamic repercussions. On ECG (Figure) we observed P-waves ...
متن کاملRight atrial cardiac rhabdomyoma with premature foramen ovale restriction: A case report
Fetal cardiac rhabdomyoma is the most common cardiac tumor in fetuses. However, this benign tumor can cause hemodynamic repercussions and intrauterine fetal mortality. The present study reports a case of rare fetal cardiac rhabdomyoma located in the right atrium, accompanied by premature restriction of the foramen ovale and moderate pericardial effusion, as determined by tomographic ultrasound ...
متن کاملDual echocardiographic determination of atrial contraction sequence in atrial flutter and other related atrial arrhythmias.
We have applied the new technique of dual echocardiography to determine the sequence of atrial contraction as reflected in the simultaneously recorded movements of the tricuspid and mitral valves. The study group included 29 normal subjects and 23 patients with either atrial flutter, coarse atrial fibrillation or atrial tachycardia with block. In normal individuals, right atrial contraction pre...
متن کاملAlternate patterns of premature ventricular excitation during induced atrial bigeminy.
SUMMARY Alternate patterns of premature ventricular excitation have been observed during induced atrial bigeminy in 18 subjects, including five normal volunteers. Each study was performed in the cardiac catheterization suite where a transvenous catheter electrode was positioned in the right atrium. Coupled or paired stimuli were delivered to the atrium by an isolated battery-powered source at a...
متن کاملA case of atrial bigeminy.
The electrocardiogram (Fig 1) reflects a basic sinus rhythm. Each sinus beat is associated with a blocked atrial extrasystole. This is evidenced by the premature and bizarre P' wave which is superimposed upon, and deforms, the S-T segment, and which is not followed by a QRS complex. The coupling interval of each extrasystole, the P-P' interval, is very short and measures 0.32 sec. The P'-P inte...
