What is capture in transcutaneous pacing?

The pads are then attached to a monitor/defibrillator, a heart rate is selected, and current (measured in milliamps) is increased until electrical capture (characterized by a wide QRS complex with tall, broad T wave on the ECG) is obtained, with a corresponding pulse.

.

Thereof, what is capture in pacing?

Electrical capture occurs when a pacing stimulus leads to depolarization of the ventricles. It is confirmed by ECG changes typical of ventricular complexes — a widening of the QRS complex and a tall, broad T wave, — displayed on the monitor (See Figures 1–3).

Similarly, what rhythms require transcutaneous pacing? How to provide transcutaneous pacing

  • hemodynamically unstable bradycardias that are unresponsive to atropine.
  • bradycardia with symptomatic escape rhythms that don’t respond to medication.
  • cardiac arrest with profound bradycardia (if used early)
  • pulseless electrical activity due to drug overdose, acidosis, or electrolyte abnormalities.

In this regard, how do you do transcutaneous pacing?

Five Step Approach to Transcutaneous Pacing

  1. Step 1: Apply the pacing electrodes and consider sedation (eg.
  2. Step 2: Turn on the monitor and set it to “pacing mode”
  3. Step 3: Select the pacing rate using the rate button (generally 60-70 bpm is adequate)
  4. Step 4: Increase current output from minimal until capture is achieved.

Do you sedation for transcutaneous pacing?

Transcutaneous cardiac pacing may be associated with discomfort such as a burning sensation of the skin, skeletal muscle contractions, or both. Because of this, patients who are conscious and hemodynamically stable should be sedated with a drug, such as midazolam, before initiation of pacing (see Procedural Sedation).
