Sinus Tachycardia and sinus bradycardia?

Question

Sinus tachycardia is NOT come from the heart. What about sinus bradycardia? Where it comes from?

Sinus tachycardia is out of the cardiologist managed as was told it comes from anxiety, stress, panic attack...... Why sinus bradycardia needs a pacemaker and cardiologist wants to involve? I'm confused!

Answer 1

Sinus bradycardia is beating of the heart slower than normal. This could be caused by several factors and has side effects such as tiredness, dizziness, and fainting. Installing a pacemaker could be one one of the ways to help speed the heart up to a normal heart beat. On the other end of the spectrum, sinus tachycardia is beating of the heart too fast. You were right when you stated that it is caused by stress. The reason that they don't put pacemakers in for people with sinus tachycardia is that it is easily cured with medications and a change in lifestyle, where as with sinus bradycarida these options are not as available as with sinus tachycardia.

To answer your first question both brady and tachycardia come from the heart, there could be other factors involved but both involve the heart.
