Too Late Allergic Reaction in a Patient with Permanent Pacemaker
1Department of Cardiology, Trakya University School of Medicine, Edirne, Turkey.
Summary
Contact allergy to cardiac implantable electronic devices, like pacemakers, is rare. This case highlights a delayed allergic reaction, diagnosed via clinical evaluation and patch testing.
Area of Science:
- Cardiology
- Dermatology
- Allergy and Immunology
Background:
- Contact allergy to cardiac implantable electronic devices (CIEDs) is an uncommon clinical issue.
- Diagnosis typically involves clinical evaluation and patch testing.
- Previous reports document allergic dermatitis developing soon after pacemaker implantation.
Observation:
- A 94-year-old male patient presented with left chest redness and itching.
- The patient had a permanent pacemaker implanted previously.
- The symptoms were indicative of a delayed allergic reaction.
Findings:
- The patient was diagnosed with contact allergy to the cardiac implantable electronic device.
- Ultrasonography supported the diagnosis.
- This case demonstrates a significantly delayed onset of allergic contact dermatitis.
Implications:
- Highlights the possibility of late-onset allergic reactions to CIEDs.
- Emphasizes the importance of considering contact allergy in patients with CIEDs presenting with dermatitis.
- Suggests that diagnostic protocols should accommodate delayed hypersensitivity reactions.

01:27Allergic Drug Reactions
1.0K
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing...

01:30Hypersensitivities
1.1K
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

01:30Cardiac Action Potential
2.9K
Cardiac action potentials are essential for proper heart function, enabling the rhythmic contractions needed for adequate blood circulation. Nodal cells and Purkinje fibers, specialized for electrical conduction, generate these action potentials.
The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.

226
Nursing responsibilities before cardiac catheterization include:Assess for allergies and establish baseline health status.Before cardiac catheterization, assess the patient for allergies to contrast dye. Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...

Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.
