Question 1

why the overpressure on the anterior fontanelle by neonatal brain ultrasound cause bradycardia of the neonate?

Accepted Answer

Cushing reflex : Increased intracranial pressure from any cause at any age &amp; decreased  blood flow to certain parts of the brain can cause Cushing's triad: increased blood pressure, irregular breathing, &amp; bradycardia. Since a neonate's skull bones aren't fused, increased pressure causes the fontanelle to bulge. Doctors will determine the cause - hydrocephalus, bleeding, infection, etc. &amp; reduce the pressure ASAP.

Question 2

what is bradycardia?

Accepted Answer

Slow heart rate: It just means a slow heart rate ( low pulse rate).

Question 3

what are causes of bradycardia?

Accepted Answer

Many: 1.  Medications 2.  High vagal tone as is present in lance armstrong 3.  Conduction system disease 4.  Infections/endocarditis with a ring abscess  5.  Sick sinus syndrome 6.  Atrio-ventricular conduction delay 7.  Abnormal electrolytes (high potassium  8.  Kindey failure.

Question 4

what are the chances of bradycardia returning?

Accepted Answer

Depends on the cause: If due to inherent dysfunction of the electrical system, it is a safe bet it will come back at some point down the road. (however, this can often flicker on and off with normal intervals of many months in between.) if caused by a reversible process, e.g. Very high potassium in the blood or very low thyroid function, then it probably won't return as long as that cause is prevented from recurring.

Question 5

what is sinus bradycardia?

Accepted Answer

Slow heart rate: A heart rate slower than expected for age when compared to a particular population that still originates from the normal region of the heart (sinus node) and travels down the normal electrical pathways of the heart.  Brady in medicine refers to slow, and in this case cardia to heart rate.

Question 6

how can you monitor bradycardia?

Accepted Answer

Bradycardia: You can monitor bradycardia in multiple ways:
1. You can feel your pulse for ten seconds (in your wrist) and multiply by six to get heart rate in beats per minute (less than sixty beats per minute defined as bradycardia)
2.  Ekg patches  can be placed on y chest (for up to one month) that records your heart rate
3. Small device can be implanted under skin upto two years to record bradycardia.

Question 7

can valsartan cause bradycardia?

Accepted Answer

Probably not: Valsartan, also called Diovan (valsartan) is an "arb" (angiotensin ii receptor antagonist) typically used for the management of hypertension and congestive heart failure. The most common side effects are dizziness and lightheadedness, but not bradycardia. Another cause of bradycardia is more likely.

Question 8

can you define sinus bradycardia?

Accepted Answer

Yes: A slow heart rate in which the electrical signal for each heartbeat originates from the sinus node (where it's supposed to originate).  Generally, in an adult, this means a heart rate of less than 60.  But keep in mind you can have a heart rate less than 60 and still be okay.  For example many good athletes, whose hearts are in great shape, have resting heart rates less than 60.

Question 9

what  causes of sinus bradycardia?

Accepted Answer

Normal or abnormal: Could be normal if physically fit  as in athletes due to high parasympathetic tone.   Abnormal sinus bradycardia could be due to degeneration of the cells in the sinus node, certain medications such as beta blockers , Diltiazem or verapamil and  sinus node ischemia( insufficient blood flow).

Question 10

what is sinus bradycardia and prwp?

Accepted Answer

ECG findings: "Sinus bradycardia" means the HR is slower than expected but otherwise normal by ECG findings.  "PRWP" stands for "poor R wave progression" - it's an ECG finding that is relatively non-specific but requires interpretation with respect to your cardiac risk factors otherwise.  If you are at elevated cardiac risk, then further testing would be recommended, such as stress testing or angiogram.
