Insights

Hypertension and atrial fibrillation (AF) increase stroke risk. A new device combining blood pressure (BP) and electrocardiogram (ECG) monitoring accurately distinguishes AF from sinus rhythm (SR) during BP measurement.

Area of Science:

  • Cardiology
  • Medical Devices
  • Hypertension Research

Background:

  • Hypertension in atrial fibrillation (AF) patients is a significant stroke risk factor.
  • Accurate differentiation between sinus rhythm (SR) and AF is crucial for patient management.
  • Existing monitoring methods may require separate devices for blood pressure (BP) and electrocardiogram (ECG).

Purpose of the Study:

  • To evaluate the accuracy of the Complete blood pressure (BP) monitor in differentiating between sinus rhythm (SR) and atrial fibrillation (AF) during BP measurement.
  • To assess the device's capability as a single-unit monitor for both BP and ECG readings.

Main Methods:

  • Fifty-six patients with persistent AF undergoing catheter ablation were enrolled.
  • Simultaneous 12-lead ECGs and Complete device recordings were obtained before and after ablation.
  • Complete device interpretations were compared against physician-reviewed ECGs, with cardiologists performing blinded reviews.

Main Results:

  • The Complete's automated algorithm achieved 100% sensitivity and 86% specificity in differentiating SR from AF (κ=0.87).
  • Physician-interpreted Complete recordings showed 99% sensitivity and 85% specificity (κ=0.85).
  • The device demonstrated high accuracy in classifying heart rhythms during BP monitoring.

Conclusions:

  • The Complete device, integrating BP and ECG monitoring, accurately differentiates between SR and AF during BP measurement.
  • This combined monitoring approach offers a promising tool for managing patients with both hypertension and AF.
  • The device's performance supports its potential utility in clinical settings for rhythm assessment.

Dysrhythmias V: Evaluating Dysrhythmias

Dysrhythmias, also known as arrhythmias, are disturbances in the heart's rhythm that range from benign to life-threatening. A thorough evaluation is crucial for appropriate management and involves a comprehensive medical history, physical examination, and various diagnostic tests.Medical HistorySymptoms: Collect detailed information on palpitations, dizziness, syncope, chest pain, and fatigue. Note their onset, frequency, and triggers.Previous Cardiac Issues: Document any history of heart...

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...

Electrocardiogram01:29

Electrocardiogram

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

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...

Measurement of Blood Pressure01:17

Measurement of Blood Pressure

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...
