Decreased pulse rate01:14

Decreased pulse rate

1.1K
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...

Dysrhythmias IV: Characteristics of Bradyarrhythmias

839
Bradyarrhythmias are cardiac rhythm disorders characterized by a slower-than-normal heart rate, typically defined as fewer than 60 beats per minute. Some of which are discussed here:Sinus BradycardiaSinus bradycardia presents a heart rate lower than 60 beats per minute, with a regular rhythm originating from the SA node. The ECG typically shows normal P waves preceding each QRS complex, a normal PR interval (0.12 to 0.20 seconds), and a normal QRS duration (0.06 to 0.10 seconds).First-Degree AV...

Noninvasive positive-pressure ventilation (NIPPV), continuous positive airway pressure (CPAP), and bilevel positive airway pressure (BiPAP) are essential methods in respiratory care. These ventilation techniques offer unique benefits for patients with various respiratory conditions, providing adequate support without requiring intubation. Let's explore how each method is crucial in improving patient outcomes and enhancing respiratory therapy.

Assessment of Ventilation
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.

Respiratory Volumes and Capacities I

2.0K
Assessing the respiratory rate and rhythm for a complete minute is crucial for evaluating the breathing pattern. Even a minor increase in the patient's average respiratory rate, by as little as three to five breaths per minute, is an early and vital indicator of respiratory distress. Patients with a respiratory rate exceeding twenty-four breaths per minute require close monitoring to determine the physiological alterations. This careful observation is essential for prompt recognition and...

Mechanical Ventilation II: Invasive Ventilation

1.2K
Ventilators are essential medical equipment used to aid patients with respiratory difficulties. Their primary function is to assist or replace spontaneous breathing by providing mechanical ventilation. There are two general classes of mechanical ventilators: negative-pressure and positive-pressure ventilators.
Negative-Pressure Ventilators
Negative-pressure ventilators create a vacuum around the chest or body to draw air into the lungs, simulating breathing. This method does not require an...

Area of Science:

  • Neurology
  • Pulmonology
  • Cardiology

Background:

  • Amyotrophic lateral sclerosis (ALS) can affect autonomic function.
  • Respiratory failure is a common complication of ALS.
  • Vasovagal syncope is a potential manifestation of autonomic dysfunction.

Purpose of the Study:

  • To describe a case of ALS with unusual autonomic and respiratory complications.
  • To explore the potential link between ALS, vasovagal episodes, and bradycardia during non-invasive ventilation.

Main Methods:

  • Case report of a patient with lower-limb onset ALS.
  • Clinical observation of respiratory failure, vasovagal episodes, and bradycardia.
  • Literature review on ALS and autonomic dysfunction.

Main Results:

  • The patient presented with respiratory failure and vasovagal episodes.
  • Recurrent profound bradycardia occurred upon removal of non-invasive ventilation.
  • Symptoms gradually resolved over ten days.

Conclusions:

  • The case highlights potential autonomic dysregulation in ALS.
  • Bradycardia during mask removal may be related to autonomic responses in ALS patients.
  • Further investigation into autonomic dysfunction in ALS is warranted.
