Arrhythmia and tachycardia are very common in pregnant women, although spinal block may be a safe anesthetic technique, severe tachycardia, cardiac arrest and other arrhythmias are reported during spinal anesthesia practices. Bupivacaine and levobupivacaine can increase the PR interval and the duration of QRS and prolong cardiac conduction. Dexmedetomidine with sympatholytic, sedative, respiratory stability without ventilatory depression, amnesic and analgesic properties, the adverse effects of dexmedetomidine are initial hypertension, hypotension, nausea, bradycardia, atrial fibrillation, pulmonary edema, oliguria and thirst. 33-year-old patient with a pregnancy of 39.2 weeks. No pathological history she received spinal anesthesia and at 10 min bradycardia of 39 corrected with atropine and later with sinus arrhythmia. In conclusion, the presence of cardiac arrhythmias can be due to several factors, the continuous monitoring and monitoring of the electrocardiogram to recognize and correct in a timely manner is transcendental.
