Electrophysiological Studies in Patients with Pulmonary Hypertension: A Retrospective Investigation

Table 3

Arrhythmias related to the pathomechanisms in patients with pulmonary hypertension and coronary heart disease.

Arrhythmia (indication for EPS)	Group 1	Group 2	Group 4
Atrial flutter	3	4 (𝑛=1)	4 (𝑛=1)
Atrial tachycardia	4	5 (𝑛=1)	1
Atrial fibrillation	—	1	—
Incisional reentry tachycardia	—	2 (𝑛=1)	—
AVNRT	3	1	—
Nonsustained VT	3 (𝑛=1)	7 (𝑛=2)	—
Monomorphic premature ventricular beats	1	1	1 (𝑛=1)
Slow VT	—	2 (𝑛=1)	—
Syncope	—	—	2 (𝑛=1)

EPS: electrophysiological study, VT: ventricular tachycardia, AVNRT: atrioventricular nodal reentrant tachycardia, 𝑛: Number of patients with coronary heart disease with coronary heart disease.
