Atropine increases the firing of the sinoatrial node (atria) and conduction through the atrioventricular node (AV) of the heart by blocking the action of the vagus nerve. With 3rd-degree block, there is a complete block and disassociation of the electrical activity that is occurring in the atria and ventricles.The use of atropine in cardiovascular disorders is mainly in the management of patients with bradycardia. Atropine increases the heart rate and improves the atrioventricular conduction by blocking the parasympathetic influences on the heart.

How does atropine worsen heart block?
The administration of atropine typically causes an increase in heart rate. This increase in the heart rate occurs when atropine blocks the effects of the vagus nerve on the heart. When the vagus nerve is blocked, the SA node increases its rate of electrical discharge and this, in turn, results in the increased HR.
What does atropine block?
Atropine is a clinically relevant anticholinergic drug, which blocks inhibitory effects of the parasympathetic neurotransmitter acetylcholine on heart rate leading to tachycardia.
What medications cause first-degree heart block?
- Class Ia antiarrhythmics (eg, quinidine, procainamide, disopyramide)
- Class Ic antiarrhythmics (eg, flecainide, encainide, propafenone)
- Class II antiarrhythmics (beta-blockers)
What medications can cause 3rd degree heart block?
- Class Ia antiarrhythmics (eg, quinidine, procainamide, disopyramide)
- Class Ic antiarrhythmics (eg, flecainide, encainide, propafenone)
- Class II antiarrhythmics (beta-blockers)
- Class III antiarrhythmics (eg, amiodarone, sotalol, dofetilide, ibutilide)
What can cause a heart block?
- Older age.
- Heart attack or coronary artery disease.
- Cardiomyopathy.
- Sarcoidosis.
- Lyme disease.
- High potassium levels.
- Severe hyperthyroidism.
- Certain hereditary neuromuscular diseases.

Is atropine contraindicated in complete heart block?
Opinions about the use of atropine in heart block generally follow one of three statements: (a) It is relatively contraindicated in high-degree blocks; (b) atropine is ineffective for high-degree blocks and should therefore not be considered; (c) the ACLS guideline says atropine should be considered, but should not …
What happens if you give too much atropine?
In overdose, atropine can cause tachycardia, agitation, delirium, dilated pupils, dry mucous membranes, dry skin, and hypoactive bowel sounds. These phenomena have been described even with attempted therapeutic ophthalmic use.
Which drug should be avoided in patients with second degree heart block?
Patients with infranodal second-degree AV block are unlikely to benefit from atropine. In addition, in patients who have denervated hearts (eg, patients who have undergone a cardiac transplant), atropine is also not likely to be effective.
Does atropine slow the heart?
Low-dose atropine slows heart rate but does not change overall levels of MSNA. High-dose atropine causes a decrease in MSNA and tachycardia.
Does atropine cause tachycardia?
Atropine acts on the M2-receptors of the heart and antagonized the activity of Ach. It causes tachycardia by blocking vagal effects on the SA node. Ach hyperpolarize the SA node which is over come by MRA and increase the heart rate. If atropine is given by intra muscular or sub cutaneous, it causes initial bradycardia.
Why atropine causes initial bradycardia?
Background: Low-dose atropine causes bradycardia either by acting on the sinoatrial node or by its effects on central muscarinic receptors increasing vagal activity.

Do beta-blockers cause heart block?
Abbreviations. Beta-blockers and nondihydropyridine calcium channels antagonists (verapamil and diltiazem) are considered a common cause of acquired complete atrioventricular (AV) block in clinical practice.

- chest pain.
- shortness of breath.
- feeling very dizzy suddenly when standing up from a lying or sitting position – this is caused by having low blood pressure (hypotension)
