Although rare, octreotide may cause mobitz
type 2 block, sinus bradycardia, and complete heart block.
Rhythm Holter showed 1 (st) degree, 2 (nd) degree (Mobitz
type 1 and 2), and 3 (rd) degree AV blocks (Figure 2A, 2B, 2C, 2D).

I, que resolvio en el transcurso de un dia, bajo vigilancia clinica y sin medidas tratamiento adicionales .
The patient had been submitted to myocardial revascularization surgery (2 years previously); first, right coronary artery angioplasty (CAA) with stent (within 11/2 year); second, CAA (within 1 year), due to intrastent restenosis; third, CAA (about 9 months before) with new restenosis and stent implantation in ACD and previous descending artery (ADA); fourth, stent implantation due to restenosis (within 3 months); and finally, 2 months ago, this patient presented second degree atrium-ventricular block (mobitz
II), being submitted to definitive artificial cardiac pacemaker implantation.

On the second day after operation, the ECG monitoring showed second-degree (Mobitz
type I) AVB with prolonged PR interval (299 ms) (Figure 1).

At the beginning of the test, sinus rhythm with first-degree to Mobitz
type II second-degree atrioventricular block was noted and no more inducible myocardial ischemia at the peak exercise that reached 85% of the maximal, age-predicted heart rate [Figure 1]f.
The exclusion criteria were patients with baseline HR< 60 bpm, those with hypovolaemia and SBP < 90 mm of Hg, those with Mobitz
type 2 and 3rd degree heart block, those with pre-existing comorbidities like cardiac, hepatic, pulmonary, neurological, endocrine or renal diseases, patients with past history of chronic hypertension, those developing Haemolysis, Elevated Liver enzymes and low platelets (HELLP syndrome), having allergy to the study drugs, history of drug abuse, use of antipsychotic or sedative medications.
type 2 block developed in the patient followed-up with ECG monitorization.
Our patient also had a first-degree AV block at baseline and was on metoprolol which was discontinued in spite of which he developed Mobitz
type II block 6 months after PCI which was completely new.
