bradycardia

Tachycardia refers to a heart rate that is too fast, generally above 100 beats per minute at rest.

Bradycardia refers to a heart rate that is too slow, generally below 60 beats per minute, though this can be perfectly normal in well-trained athletes.

Atrial fibrillation is one of the most common arrhythmias, in which the atria quiver irregularly instead of contracting in a coordinated fashion.

Instead of a smooth, rhythmic squeeze, the atria flutter chaotically, and the heartbeat becomes irregular and often too fast.

So sinus rhythm, it's early.

Bradycardia, it's becoming slightly later.

And by the time you get into agonal rhythms and asystole, it's at least 10 minutes since that point in time, which we're going to take as the start of this decision making.

It may be there's not a medical personnel on scene initially, so that time zero is really difficult to gain.

Backflow keeps going further back into the lungs, causing pulmonary edema.

Bradycardia is dangerous in these patients because it prolongs the regurgitant time.

Avoid bradycardia.

Afterload reduction can help these patients.

Now, let's take a look at dopamine.

When used for the treatment of unstable bradycardia, dopamine is a second-line drug to atropine.

It may only be needed till TCP can be started.

When used for the treatment of hypotension, dopamine can be used longer while we attempt to identify and correct the hypotension's underlying cause.

This could signal physiologic stress, severe pain, fever, or cardiac instability.

Bradycardia is a slower than normal rate, under sixty beats per minute, which might indicate reduced cardiac output, though it can be normal in highly trained athletes.

We also need to know exactly where to find these arterial pulse points.

The radial pulse, located on the thumb side of the anterior wrist, is the most accessible and common site for routine checks.

Before we could debate someone, or something, clattered overhead in the tightest crawlspace, dislodging old bolts.

Bradycardia hit me.

My heart tried to leap clear of my ribs.

Then footsteps, slow and wet, dragging, retreated backward rather than coming closer.
