Pulse rhythm

Pulse rhythm

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...

Pulse

Pulse

When the heart pumps blood out, arterial elastic fibers play a crucial role in sustaining a high-pressure gradient. They expand to accommodate the received blood and then recoil - a process known as the pulse that can be either manually palpated or electronically quantified. Despite a reduction in its effect with increased distance from the heart, elements of the pulse's systolic and diastolic components persist, observable even at the arteriole level.
The pulse serves as a clinical...

Equipments Used To Measure Blood Pressure

Equipments Used To Measure Blood Pressure

Direct Method
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

Regulation of Pulse

Regulation of Pulse

Pulse regulation involves physiological mechanisms that ensure adequate blood flow throughout the body. The heartbeat, regulated by the autonomic nervous system, is influenced by hormonal balance, physical activity, and emotional state.

Decreased pulse rate

Decreased pulse rate

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...

Summary

Conduction system pacing offers a physiological alternative to conventional pacing, potentially reducing heart failure risk. Techniques like His bundle pacing and left bundle branch area pacing show promise but require careful patient selection and operator skill.

Area of Science:

Cardiology
Electrophysiology
Medical Devices

Background:

Conventional right ventricular pacing is linked to cardiomyopathy and heart failure.
There's a need for alternative pacing methods to improve patient outcomes.

Purpose of the Study:

To evaluate conduction system pacing (CSP) as a physiological alternative to conventional pacing.
To compare His bundle pacing and left bundle branch area pacing (LBBAP) for patients with reduced ejection fraction and dyssynchrony.

Main Methods:

Review of His bundle pacing and LBBAP techniques, their advantages, disadvantages, and electrical parameters.
Analysis of patient selection criteria, operator learning curves, and complication rates.
Consideration of current European Society of Cardiology (ESC) guidelines regarding CSP.

Main Results:

His bundle pacing achieves a native QRS complex but is technically challenging.
LBBAP is technically simpler but associated with mechanical complications and wider QRS.
CSP is safe and effective with careful patient selection and training, despite a higher complication rate than conventional pacing.

Conclusions:

Conduction system pacing, including His bundle pacing and LBBAP, offers physiological pacing benefits.
Current guidelines recommend CSP in specific scenarios, such as failure of resynchronization therapy or for patients with AV block and reduced ejection fraction.
Further research is needed to fully define the role of CSP in cardiac pacing.
