Studies have shown that patients with Pacemaker syndrome and/or with sick sinus syndrome are at higher risk of developing fatal complications that calls for the patients to be carefully monitored in the ICU. Complications include atrial fibrillation, thrombo-embolic events, and heart failure. [7]
The hexaxial reference system is a diagram that is used to determine the heart's electrical axis in the frontal plane.. In electrocardiography, left axis deviation (LAD) is a condition wherein the mean electrical axis of ventricular contraction of the heart lies in a frontal plane direction between −30° and −90°.
Junctional rhythms (if a bradycardia) can cause decreased cardiac output. Therefore, the person may exhibit signs and symptoms similar to other bradycardia such as lightheadedness, dizziness, low blood pressure, and fainting. This rhythm can usually be tolerated if the rate is above 50 beats per minute. [citation needed]
[citation needed] Most stable patients have persistent bradycardia-related symptoms and require identification and treatment of any reversible cause or permanent implantable pacemaker. Reversible causes of complete AV block should be ruled out before the insertion of a permanent pacemaker, such as drugs that slow heart rate and which induce ...
An ectopic pacemaker located in the atria is known as an atrial pacemaker and can cause the atrial contraction to be faster. [10] An ectopic pacemaker situated near the AV node and the septum is known as a junctional pacemaker. [11] The pacemaker that is operating in the ventricles is known as the ventricular. [12]
Patients with first-degree AV block do not have any resulting severe or life-threatening symptoms, such as symptomatic bradycardia or hypotension, and, thus, do not require treatment. [1] Similarly, patients with second-degree Mobitz I AV block rarely develop life-threatening symptoms, and patients who are asymptomatic do not require treatment ...
Exaggerated stress responses may contribute to the increased incidence of hypertension in this group. [35] For patients having hypertension, higher heart rate variability (HRV) is a risk factor for atrial fibrillation. [36] Resistant hypertension can be treated by electrically stimulating the baroreflex with a pacemaker-like device. [37]
The symptoms and signs of hypertensive heart disease will depend on whether or not it is accompanied by heart failure. In the absence of heart failure, hypertension, with or without enlargement of the heart (left ventricular hypertrophy) is usually symptomless. [citation needed] Symptoms, signs and consequences of congestive heart failure can ...
