Autonomic Nervous System Monitoring: Failed Clinical Utility

As the title may suggest the use of ANS monitoring may not lead to accurate clinical diagnosis and treatment for many ailments. What is missing from this title is the fact that without measuring the Parasympathetic nervous system in total and independently, a correct diagnosis would not be provided. This problem exists in the industry […]

Cardiac Autonomic Testing And Treating Heart Disease. “A Clinical Perspective” 2 Of 2

Abstract Background Coronary heart disease (CHD) is a major health concern, affecting nearly half the middle-age population and responsible for nearly one-third of all deaths. Clinicians have several major responsibilities beyond diagnosing CHD, such as risk stratification of patients for major adverse cardiac events (MACE) and treating risks, as well as the patient. This second

Cardiac Autonomic Testing And Diagnosing Heart Disease. “A Clinical Perspective” 1 Of 2

Abstract Background Coronary heart disease (CHD) is a major health concern, affecting nearly half the middle-age population and responsible for nearly one-third of all deaths. Clinicians have responsibilities beyond diagnosing CHD, including risk stratification of patients for major adverse cardiac events (MACE), modifying the risks and treating the patient. In this first of a two-part

Differential Effects of Adrenergic Antagonists (Carvedilol vs. Metoprolol) on Parasympathetic and Sympathetic Activity: A Comparison of Measures 1 of 2

BACKGROUND  Cardiovascular autonomic neuropathy (CAN) is recognized as a significant health risk. Specific and sensitive measures of CAN are needed for early identification and treatment to avoid complications, preferably in the preclinical state.  OBJECTIVES  In this first of two articles, the patient cohort is described and two measures of autonomic function are reviewed: the traditional

Differential Effects of Adrenergic Antagonists (Carvedilol vs. Metoprolol) on Parasympathetic and Sympathetic Activity: A Comparison of Measures 2 of 2

BACKGROUND  Cardiovascular autonomic neuropathy (CAN) is recognized as a significant health risk, correlating with risk of heart disease, silent myocardial ischemia or sudden cardiac death. Beta-blockers are often prescribed to minimize risk.  OBJECTIVES  In this second of two articles, the effects on parasympathetic and sympathetic activity of the alpha/beta-adrenergic blocker, Carvedilol, are compared with those

Clinical Autonomic Dysfunction

PART 1: Introduction and History of Autonomic Nervous System Monitoring CHAPTER 1: Introduction to Parasympathetic and Sympathetic Monitoring This introductory section starts with a review of the “Old School” information commonly taught in medical school, including the anatomy of the autonomic nervous system (ANS) and its two branches, the parasympathetic and sympathetic nervous systems; the
