Case Reports in Cardiology
|March 11, 2015
Summary
Interatrial block (IAB), a delay in heart signal conduction, can be intermittent. This study presents two cases of patients undergoing chronic hemodialysis who experienced intermittent IAB, highlighting a potential link.
Area of Science:
- Cardiology
- Electrophysiology
Background:
- Interatrial conduction delays cause prolonged P-wave duration on ECG.
- Interatrial block (IAB) describes these delays, which are typically fixed but can be intermittent.
- Intermittent IAB suggests functional conduction issues, potentially at the Bachmann bundle.
Purpose of the Study:
- To report cases of intermittent interatrial block (IAB) in patients on chronic hemodialysis.
- To explore the association between chronic hemodialysis and intermittent IAB.
Main Methods:
- Case report of two patients undergoing chronic hemodialysis.
- Electrocardiogram (ECG) analysis to identify intermittent interatrial block (IAB).
Main Results:
- Both patients presented with intermittent interatrial block (IAB).
- The findings suggest a possible connection between chronic hemodialysis and the occurrence of intermittent IAB.
Conclusions:
- Chronic hemodialysis may be associated with intermittent interatrial block (IAB).
- Further research is warranted to understand the mechanisms linking hemodialysis and conduction delays.

2.0K
DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

3.7K
Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...

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...

The nursing management of a patient undergoing hemodialysis includes several critical steps, starting with a thorough assessment before the procedure.Before the Hemodialysis ProcedureFirst, record the patient's vital signs—blood pressure, heart rate, respiratory rate, and temperature—to establish a baseline. This baseline is essential for detecting conditions such as hypotension that could impact the patient's response to dialysis. Document the patient's pre-dialysis weight, as this...

01:22Antiarrhythmic Drugs: Class I Agents as Sodium Channel Blockers
4.3K
Class I antiarrhythmic drugs are used to treat various types of arrhythmias or irregular heart rhythms. These drugs block the sodium (Na+) channels in the cardiac cells, thereby affecting the movement of electrical impulses across the heart. Class I antiarrhythmic drugs are divided into three subgroups: Class IA, Class IB, and Class IC, each with distinct mechanisms of action and effects on the heart.
Class 1A Antiarrhythmic Drugs: These drugs work by moderately blocking sodium channels,...

01:12Antiarrhythmic Drugs: Class III Agents as Potassium Channel Blockers
3.0K
Class III antiarrhythmic drugs are a group of medications that can prolong action potentials in the heart. They achieve this by blocking potassium channels or enhancing inward currents from sodium channels. However, these drugs have a unique property of "reverse use-dependence," which is most pronounced at slower heart rates and can lead to torsades de pointes—a specific type of arrhythmia. However, it is essential to note that excessive QT interval prolongation—a measure of...
