Does anyone know what sinus bradycardia is, and what can cause it?

Question

Is it possible that a known medication that you are allergic to could cause this ?

Answer 1

slow heart rate can be caused by medications, sick sinus syndrome and even a heart attack, allergies do not cause bradycardia. good luck

Answer 2

What is Sinus Bradycardia:

periods of heartbeats that are too quick

Causes of Sinus Bradycardia:


1. Normal pattern in healthy adults and athletes
1. Baseline Bradycardia suggests physical conditioning
2. Other causes of sinus Bradycardia
1. Hypothermia
2. Severe infection
3. Jaundice
4. Carotid Sinus Hypersensitivity
1. Tight shirt collar
5. Excessive parasympathetic stimulation
1. Acute inferior wall Myocardial Infarction
6. Decreased sympathetic stimulation (medications)

# Diagnostics: EKG Findings

1. Regular rhythm with rate at <50 to 60 beats per minute
2. Normal and consistent P-wave morphology
3. Normal PR-Interval duration

Answer 3

The term sinus means that the electical impulse (heart rate) originates from the sinus node, which is located in the right atrium. Bradycardia relates to the rate, defined is less than 60 beats per minute.

There are too many reasons to enumerate on why someones heart rate may decrease. Allergies do not directly decrease the heart rate. For example, Over medication or sensitivity to certain medications can cause a slow heart rate. Contact your doctor for evaluation.

Hope this helps!!

Answer 4

Sinus bradycardia is a heart rate under 60. People who are extremely physically fit have low heart rates under 60
Some people have low heart rates due to heart blocks which may or may not require a pacemaker.
Many people are on medications called beta blockers for hypertension which can cause sinus bradycardia.
People who are on Digoxin (lanoxin) can become bradycardic from the medication.
Allergic reaction to meds do not cause bradycardia.

Answer 5

Background:
Sinus bradycardia can be defined as a sinus rhythm with a resting heart rate of 60 beats/minute or less. However, few patients actually become symptomatic until their heart rate drops to less than 50 beats/minute. The action potential responsible for this rhythm arises from the sinus node and causes a P wave on the surface ECG that is normal in terms of both amplitude and vector. These P waves are typically followed by a normal QRS complex and T wave.

Sinus bradycardia may also be caused by the sick sinus syndrome, which involves a dysfunction in the ability of the sinus node to generate or transmit an action potential to the atria. Sick sinus syndrome includes a variety of disorders and pathologic processes that are grouped within one loosely defined clinical syndrome. The syndrome includes signs and symptoms related to cerebral hypoperfusion, in association with sinus bradycardia, sinus arrest, sinoatrial (SA) block, carotid hypersensitivity, or alternating episodes of bradycardia and tachycardia.

Frequency:
In the US: Frequency of sinus bradycardia is unknown, given that most cases represent normal variants. Although the frequency of sick sinus syndrome is unknown in the general population, in cardiac patients it has been estimated to be 3 in 5000.
Mortality/Morbidity: Sequelae of sinus bradycardia are related to its underlying etiology.

In patients who present with toxic exposure, the prognosis is good once the offending agent has been removed.
Patients with sick sinus syndrome have a relatively poor prognosis, with 5-year survival rates in the range of 47-69%. However, whether this mortality is due to factors intrinsic to the sinus node itself or the concomitant heart disease is unclear.

History:
Sinus bradycardia is most often asymptomatic. However, symptoms may include the following:
Syncope, Dizziness, Lightheadedness, Chest pain
Shortness of breath
Pertinent elements of the history include the following:
Previous cardiac history (eg, myocardial infarction, congestive heart failure, valvular failure),
Medications, Toxic exposures,Prior illnesses

Answer 6

Heart rate less than 60. It is normal in some people--like athletes. Some medications could cause it (like if you're on too much), but I don't know about an allergy to one. Usually an allergic reaction will speed up a heart rate.

Answer 7

Yes but you need to see your doctor. Go to WEBMD.com and look up the term to find out more about it. or just google the term. Essentially its a regluar slow heart beat, its better that the other option. Medications can be used to treat this and increase it if needed. Get the info and talk with your MD.

Answer 8

Slow heart rate

Answer 9

i could explain but it's easier to show you lol....click there
