I take 25 mg of atenolol in the morning and 25 mg at night and my heart rate gets down to 52. I am wondering,if I took about 15-20 25 mg tablets at one time,would my heart rate drop down to 0? Could it cause me to faint and not wake up?

Symptoms of overdose are due to excessive pharmacodynamic actions on β1 and also β2-receptors. These include bradycardia, severe hypotension with shock, acute heart failure, hypoglycemia and bronchospastic reactions. Treatment is largely symptomatic. Hospitalization and intensive monitoring is indicated. In early cases emesis can be induced. Activated charcoal is useful to absorb the drug. Atropine will counteract bradycardia, glucagon helps with hypoglycemia, dobutamine can be given against hypotension and the inhalation of a β2-mimetic as hexoprenalin or salbutamol will terminate bronchospasms. Blood or plasma atenolol concentrations may be measured to confirm a diagnosis of poisoning in hospitalized patients or to assist in a medicolegal death investigation. Plasma levels are usually less than 3 mg/L during therapeutic administration, but can range from 3–30 mg/L in overdose victims.

No,Even you took the whole 20 tablets,your heart will not stop directly or right the way.Why?Let me tell you.Atenolol is one kind of nomslective beta-adrenergic recepter blocking agent.That mean it block the action of beta-adrenergic agent it including beta1 and beta2 action.beta-ad action are keep the heart rate,heart museles strength and restrict the blood vessel and keep the blood pressure.It also work on other organ;lung,gi tract urinary tract.If block this effect the heart will slow down the vessel will dilate but the heart will not completely stop because other adrenergic recepter still open such as alfa 1 and alfa 2 and dopamin all those adrenergic action will keep the heart still beating.Beta blocker toxicity patient will have a lot of suffering.
