Beta blocker
Beta blockers, also written β-blockers, are a class of medications that are particularly used to manage abnormal heart rhythms, and to protect the heart from a second heart attack (myocardial infarction) after a first heart attack (secondary prevention).

Bradycardia
Bradycardia is a condition wherein an individual has a very slow heart rate, typically defined as a resting heart rate of under 60 beats per minute (BPM) in adults.

Drug
A drug is any substance (other than food that provides nutritional support) that, when inhaled, injected, smoked, consumed, absorbed via a patch on the skin, or dissolved under the tongue causes a temporary physiological (and often psychological) change in the body.

Epileptic seizure
An epileptic seizure is a brief episode of signs or symptoms due to abnormally excessive or synchronous neuronal activity in the brain.

Grayanotoxin
Grayanotoxins are a group of closely related neurotoxins named after Leucothoe grayana, a plant native to Japan originally named for 19th century American botanist Asa Gray.

Heart rate
Heart rate is the speed of the heartbeat measured by the number of contractions of the heart per minute (bpm).

Hypotension
Hypotension is low blood pressure, especially in the arteries of the systemic circulation.
New!!: Sinus bradycardia and Hypotension · See more »
Hypothermia
Hypothermia is reduced body temperature that happens when a body dissipates more heat than it absorbs.
New!!: Sinus bradycardia and Hypothermia · See more »
Hypothyroidism
Hypothyroidism, also called underactive thyroid or low thyroid, is a disorder of the endocrine system in which the thyroid gland does not produce enough thyroid hormone.

Lightheadedness
Lightheadedness is a common and typically unpleasant sensation of dizziness and/or a feeling that one may faint.

Long QT syndrome
Long QT syndrome (LQTS) is a condition which affects repolarization of the heart after a heartbeat.

Myocarditis
Myocarditis, also known as inflammatory cardiomyopathy, is inflammation of the heart muscle.

P wave (electrocardiography)
The P wave in the ECG represents atrial depolarization, which results in atrial contraction, or atrial systole.
New!!: Sinus bradycardia and P wave (electrocardiography) · See more »
PR interval
In electrocardiography, the PR interval is the period, measured in milliseconds, that extends from the beginning of the P wave (the onset of atrial depolarization) until the beginning of the QRS complex (the onset of ventricular depolarization); it is normally between 120 and 200ms in duration.

QRS complex
The QRS complex is a name for the combination of three of the graphical deflections seen on a typical electrocardiogram (EKG or ECG).

Sick sinus syndrome
Sick sinus syndrome (SSS), also called sinus dysfunction, or sinoatrial node disease ("SND"), is a group of abnormal heart rhythms (arrhythmias) presumably caused by a malfunction of the sinus node, the heart's primary pacemaker.
