Solution: false, there are a lot of other reasons
Extra Information / Pictures:
โPalpitations are differently perceived by patients, they being able to describe rapid heartbeats or heart rhythm irregularities. Irregularities are perceived like sudden pauses in cardiac activity, eventually followed by a strong precordial beat or at the level of throat vessels, usually due to increased preload and contractility following atrial or ventricular extrasystole with increased systolic output. Palpitations may appear without rhythm disorders, within the above mentioned hyperkinetic syndromes but also in case of precordial muscular fasciculation that may result in palpitations (especially in patients with necrosis or hypocalcemia) so suggestive for rhythm disorders. Of course, pulse palpation or auscultation quickly make diagnosis.โ

HFrEF (<40%)= systolic heart failure +- LV dilated
Diagnosis of Heart Failure with Reduced Ejection Fraction (HF-REF) requires three conditions to be satisfied:
- Symptoms typical of heart failure
- Signs typical of heart failure
- Reduced left ventricular (LV) ejection fraction
HFpEF (>50%) = diastolic HF (hypertension-assoc. LV hypertrophy or primary cardiomyopathy)
Diagnosis of Heart Failure with Preserved Ejection Fraction (HF-PEF) requires four conditions to be satisfied:
- Symptoms typical of heart failure
- Signs typical of heart failure
- Normal or only mildly reduced LV ejection fraction with LV not dilated
- Relevant structural heart disease (LV hypertrophy/left atrial enlargement) and/or diastolic dysfunctionโ
Heart failure is categorized into several types based on left ventricular ejection fraction (LVEF). These types include:
- Heart failure with reduced ejection fraction (HFrEF): LVEF < 40%
- Heart failure with preserved left ventricular ejection fraction (HFpEF): LVEF > 50% (also known as diastolic heart failure): This type is commonly seen in elderly hypertensive patients and those with primary cardiomyopathies such as hypertrophic, restrictive, and infiltrative cardiomyopathies.
- Heart failure with mid-range ejection fraction (HFmrEF): LVEF between 40% and 50%
- Right ventricular systolic dysfunction (RVSD): This refers to the impaired function of the right ventricle.
- Chronic Cor Pulmonale: This is a condition characterized by right ventricular enlargement and dysfunction due to chronic pulmonary hypertension.

intranodal
Intranodal blocks, which involve interruption of impulse transmission within the atrioventricular (AV) node, have a better prognosis compared to infranodal or infrahisian blocks. Intranodal blocks allow for a "escape" rhythm with a rate of 45-50 beats per minute, which is sufficient for the patient to remain awake and engage in regular activities. On the other hand, infranodal or infrahisian blocks result in a ventricular escape rhythm with a rate of 10-30 beats per minute, which can lead to long pauses and a higher risk of asystole and death.

AV block
As a general rule, the more severe forms of acquired AV-block, such as Mobitz I block, "high grade" AV block, and complete AV block, are closely associated with syncope. These conditions are characterized by disturbances in the conduction of electrical signals between the atria and ventricles of the heart.

Coronary ischemia causes abnormalities in electrical activity (electrocardiographic ischemic abnormalities; rhythm disorders), heart function (systolic or diastolic dysfunction), and chest pain. These manifestations are associated with coronary artery disease and have clinical implications.
Coronary ischemia can result in various electrocardiographic changes indicating myocardial ischemia. These changes may include ST-segment depression or elevation, T-wave inversion, or pathological Q waves. These findings help diagnose myocardial infarction and guide management.
Systolic or diastolic dysfunction can occur due to coronary ischemia. Systolic dysfunction impairs heart muscle contraction, reducing stroke volume and cardiac output. Diastolic dysfunction involves impaired ventricular relaxation or increased stiffness, affecting filling and ventricular compliance.
Chest pain, known as angina, is a common symptom of coronary ischemia. It is described as a pressure-like or squeezing sensation in the chest that may radiate to the left shoulder, arms, abdomen, or neck. Prompt recognition and management of chest pain are crucial for preventing complications and ensuring optimal outcomes.

In severe or refractory cases, surgical treatment (septal myectomy) or DDD pacing (with initial stimulation of the right ventricle, resulting in paradoxical movement of the interventricular septum during systole and a reduction in the degree of subaortic dynamic stenosis with decreased left ventricular outflow tract obstruction) can be considered. An alternative to surgery is alcohol septal ablation, which involves the infusion of pure alcohol into a major septal branch of the left anterior descending artery (LAD), inducing a localized "septal infarction" that leads to a reduction in the thickness of the interventricular septum and the degree of systolic obstruction. ๐ท

Aortic Dissection (AoD) is a condition where the layers of the aorta separate due to a tear in the aortic intima. ๐ท This tear exposes the diseased medial layer to the force of blood pressure, causing it to penetrate and cleave the aortic wall, creating a false lumen. ๐ท
Alternatively, AoD can begin with the rupture of vaso-vasorum, leading to the development of an intramural hematoma and subsequent intimal tear.
โ. ๐ท
Type | Description | Recommended Treatment |
Type I | Dissection starts in the ascending aorta and propagates distally to include at least the aortic arch and typically the descending aorta | Surgery |
Type II | Dissection starts in and is confined to the ascending aorta | Surgery |
Type III | Dissection starts in the descending aorta and propagates most often distally | Nonsurgical treatment |
Type IIIa | Dissection is limited to the descending thoracic aorta | Nonsurgical treatment |
Type IIIb | Dissection extends below the diaphragm | Nonsurgical treatment |
โ ๐ท
The Stanford classification divides dissections into two categories based on the involvement of the ascending aorta:
Type A: Dissections that involve the ascending aorta, regardless of the site of origin. Surgical treatment is usually recommended for type A dissections.
Type B: Dissections that do not involve ascending aorta. Nonsurgical treatment is usually recommended for type B dissections.

- Age is an important risk factor for abdominal aortic aneurysms (AAA), with the incidence rising rapidly after 55 years of age in men and 70 years of age in women.
- Smoking is also associated with the risk of AAA, with the duration of smoking being a contributing factor.
- Male gender, hypertension, and hyperlipidemia are other factors that have been linked to the development of AAA.
- Atherosclerosis is widely considered to be the underlying cause of abdominal aortic aneurysms, with the infrarenal abdominal aorta being the most commonly affected area.
