Standing Waves01:17

Standing Waves

5.0K
Sometimes waves do not seem to move; rather, they just vibrate in place. Unmoving waves can be seen on the surface of a glass of milk kept in a refrigerator, which is one example of standing waves. Vibrations from the refrigerator motor create waves on the milk that oscillate up and down but do not seem to move across the surface. These waves are formed or created by the superposition of two or more identical moving waves in opposite directions. The waves move through each other, with their...

Voltammetric Techniques: Pulse Voltammetry

1.1K
Differential-pulse voltammetry (DPV) is a type of voltammetry that involves applying a series of voltage pulses to an electrochemical cell while measuring the resulting current. In DPV, the differential pulse or small potential pulses are superimposed on a linear potential sweep. The magnitude of these pulses is typically small, often in the millivolt range. Each voltage pulse lasts a short duration, usually in the order of a few milliseconds, and is applied at regular intervals along the...

Electrocardiogram01:29

Electrocardiogram

4.8K
An electrocardiogram (ECG or EKG) is a critical diagnostic tool that records the electrical signals produced by the heart during each heartbeat. This recording is achieved through electrodes placed strategically on the arms, legs, and chest. The electrocardiograph amplifies these signals and produces 12 distinct tracings, offering a comprehensive understanding of the heart's electrical activity.
Three major waveforms are present in a typical ECG recording: the P wave, the QRS complex, and...

Pulse rhythm01:30

Pulse rhythm

1.1K
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...

Pulse01:16

Pulse

1.7K
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...

Area of Science:

  • Cardiovascular Physiology
  • Medical Diagnostics

Background:

  • Arterial pulse interpretation has been a cornerstone of medical examination since antiquity.
  • Graphic pulse wave recording methods were pioneered by Marey and Mahomed.
  • Mahomed utilized pulse recordings to identify hypertension and study its natural history.

Purpose of the Study:

  • To review the historical and modern applications of pulse wave analysis.
  • To highlight the resurgence of interest in pulse wave analysis due to limitations of cuff sphygmomanometry.
  • To emphasize advancements in non-invasive measurement techniques and hemodynamic understanding.

Main Methods:

  • Historical review of pulse wave recording techniques.
  • Introduction of high-fidelity tonometers for accurate, non-invasive pulse contour measurement.
  • Application of modern understanding of arterial hemodynamics and aging effects.

Main Results:

  • Pulse wave analysis can now be accurately performed non-invasively in peripheral arteries.
  • Ascending aortic waveforms can be synthesized, and systolic/diastolic periods identified.
  • Indices of ventricular-vascular interaction, previously requiring invasive methods, are now obtainable.

Conclusions:

  • Modern pulse wave analysis provides more accurate diagnosis than historical methods.
  • Advancements enable more logical and precise therapeutic strategies.
  • Non-invasive pulse wave analysis offers superior diagnostic and therapeutic capabilities compared to cuff-based methods.
