===Family History===
===Family History===
A family history could provide important information not only in atherosclerotic cardiovascular disease but also for many other cardiac diseases. For example, congenital heart diseases are more common in the offspring of parents, family members or siblings. Genetic diseases, such as neuromuscular disorders, connective tissue disorders (eg, Marfan syndrome), lipid metabolism disorders can affect the cardiovascular system as well [chapter congenital heart disease].

===Syncope and Pre-syncope===
===Syncope and Pre-syncope===
Light-headedness, dizziness, pre-syncope, and syncope are important symptoms, often caused by a reduction in cerebral blood flow. The mentioned symptoms are nonspecific and can be due to a broad caused by a broad range of underlying pathophysiology such as metabolic conditions, dehydration, primary central nervous system disease, or inner-ear problems. Because bradyarrhythmias and tachyarrhythmias are important cardiac causes of these symptoms, they are of importance in the cardiovascular examination. A careful history taking, including preceding symptoms such as palpitations or chest pain, are of great importance. Further information on this topic can be found in [[http://www.textbookofcardiology.org/wiki/Syncope]].

===Palpitation===
===Palpitation===
Cardiac activity usually cannot be experienced by individuals in normal resting condition. If a patient is aware of its heart activity it is usually referred to as palpitation. Among cultures and patients there is no standard definition for the type of sensation represented by palpitation. It is often very illustrative to ask the patients to tap with their hand the perceived heartbeat. Most commonly palpitations are caused by an unusually forceful heart beat at a normal rate (60–100 bpm). When a patient senses more forceful contractions as usual without a significant increased heart rate, the palpitations are most commonly the result of endogenous catecholamine excretion. A customary cause of this phenomenon is anxiety. Another common experienced feeling is that of the heart stopping transiently and/or the occurrence of isolated forceful beats. The nature of this sensation is usually premature ventricular contractions. The rapid regular or irregular heart rates most linked to the term “palpitations” are the least common sensation reported by individual patients and is usually supraventricular of origin. More information on palpitations caused by arrhythmias can be found in the subsequent chapter [link arrhytmias].
