Pulse rhythm01:30

Pulse rhythm

1.6K
Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

Tachycardia is a condition marked by an abnormally fast or irregular heart rate, surpassing the typical resting rate. In adults, tachycardia is characterized by a pulse rate ranging from 100 to 180 beats per minute. The increased heart rate can result in inadequate blood flow to various body parts, ultimately diminishing the oxygen supply to organs and tissues.
Many factors can elevate the risk of developing tachycardia. These include advanced age, a family history of arrhythmias, and an...

Bradycardia is a medical condition in which the heart rate is slower than normal. It occurs when the heart's natural pacemaker, the sinus node, generates slower electrical impulses than the standard rhythm. In adults, bradycardia is diagnosed when the pulse rate falls below 60 beats per minute, indicating a deviation from the normal heart rate range.
There are specific risk factors that can elevate the likelihood of developing bradycardia. Advanced age is a significant factor, with...

Pulse Assessment Sites01:11

Pulse Assessment Sites

3.1K
Pulse assessment sites are crucial in evaluating a patient's cardiovascular health. By assessing the pulsations of arteries at specific anatomical locations, healthcare professionals can gather valuable information about blood flow, heart rate, and peripheral circulation. Understanding these pulse assessment sites is essential for conducting comprehensive cardiovascular evaluations and monitoring patients' overall health. These sites are strategically chosen due to the accessibility and...

Area of Science:

  • Cardiology
  • Electrophysiology
  • Cardiac Pacing

Background:

  • Traditional right ventricular pacing can impair cardiac pump function and lead to heart failure due to prolonged ventricular activation.
  • His bundle pacing, a newer technique, aims to mimic the heart's natural electrical conduction pathway.

Purpose of the Study:

  • To review the techniques, feasibility, outcomes, and clinical impact of permanent His bundle pacing.
  • To compare His bundle pacing with traditional right ventricular pacing.

Main Methods:

  • Review of existing literature on His bundle pacing techniques.
  • Analysis of patient outcomes and clinical data from studies on His bundle pacing.
  • Discussion of the physiological benefits of His bundle pacing over right ventricular pacing.

Main Results:

  • His bundle pacing maintains a near-normal ventricular activation sequence, unlike right ventricular pacing.
  • This preserved activation pattern mitigates the negative effects on cardiac pump function associated with traditional pacing.
  • His bundle pacing demonstrates feasibility and positive outcomes in selected patient populations.

Conclusions:

  • Permanent His bundle pacing is a viable and potentially advantageous alternative to right ventricular pacing.
  • It effectively prevents pacing-induced heart failure by preserving physiological ventricular activation.
  • Further research and clinical adoption are warranted for this advanced pacing strategy.
