Pulse01:16

Pulse

1.1K
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...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

59
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

Measurement of Blood Pressure01:17

Measurement of Blood Pressure

1.5K
Assessing blood pressure is a standard procedure executed in virtually all medical environments. The method utilized today was established over a hundred years ago by an innovative Russian doctor, Dr. Nikolai Korotkoff. The soft ticking noise, known as Korotkoff sounds, heard while taking blood pressure readings results from turbulent blood flow within the vessels. The apparatus required for this procedure includes a sphygmomanometer, a blood pressure cuff attached to a gauge, and a...

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

Regulation of Pulse01:20

Regulation of Pulse

1.5K
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.

Pulse amplitude and quality01:17

Pulse amplitude and quality

2.2K
Pulse amplitude is a crucial indicator of cardiac health because it provides valuable insights into the strength of left ventricular contractions and the overall uniformity of blood circulation within the vasculature. The strength of the pulse is directly related to the force with which the heart contracts and the volume of blood being pumped.
A weak or absent pulse may indicate reduced cardiac output or poor left ventricular contraction, which can be signs of cardiovascular dysfunction or...

Summary

Pulsatile tinnitus (PT), a heartbeat-synchronized sound perception, often stems from vascular issues. Early diagnosis and treatment, including minimally invasive procedures, can significantly improve quality of life for most patients.

Area of Science:

  • Neurology
  • Otolaryngology
  • Vascular Medicine

Background:

  • Pulsatile tinnitus (PT) is a rare form of tinnitus, accounting for 4% of cases, characterized by sound perception synchronized with the heartbeat.
  • Common causes include vascular abnormalities such as carotid stenosis, idiopathic intracranial hypertension, sinus stenosis, aneurysms, and arteriovenous malformations.
  • PT significantly impacts patient quality of life, often causing psychological distress, even when not life-threatening.

Purpose of the Study:

  • To review the diverse etiologies of pulsatile tinnitus.
  • To outline current diagnostic strategies for identifying the origin of PT.
  • To summarize available management and treatment options for pulsatile tinnitus.

Main Methods:

  • This narrative review synthesizes information from existing literature on pulsatile tinnitus.
  • It analyzes the common and less common causes of PT.
  • The review discusses the diagnostic pathway and therapeutic interventions.

Main Results:

  • Vascular abnormalities are the most frequent causes of pulsatile tinnitus.
  • A comprehensive history, clinical examination, and targeted imaging are crucial for diagnosis.
  • While a specific cause remains unidentified in about 30% of cases, many patients benefit from treatment.

Conclusions:

  • Pulsatile tinnitus necessitates a thorough diagnostic evaluation to identify treatable vascular or other underlying causes.
  • Minimally invasive endovascular procedures and surgical interventions show promise in managing PT.
  • Effective management of PT is essential for improving patients' overall quality of life and reducing psychological disturbances.
