Heart palpitations at night

Why do we have heart palpitations at night?

Before we discuss the matter of heart palpitations at night, we have to clarify the meaning of the word “palpitation” in general. Palpitations refer to irregular heart beats, usually the heart beats to fast, or with pauses from time to time and gives us an abnormal sensation, sometimes associated with dizziness, light-headed sensation, shortness of breath, chest pain etc.
We all had palpitation at least once in our life, and this doesn’t mean we have a heart disease, because these symptoms occur in healthy people during exercise or associated to stress, smoking, coffee. Even so, if the palpitation persist or are associated with shortness of breath, chest pain, fainting, dizziness, a doctor should be consulted as soon as possible.
Some patients complain they have heart palpitations at night, which prevent them from falling asleep or wake them up in the middle of the night.

Heart palpitations at night -causes:

Normal heart rate for an adult is 60-90 beats/minute. If the heart rate is higher the 90 beats per minute, then the condition is called tachycardia and can provoke palpitation. Not only rapid heart rate can cause palpitation but also irregular heart beats, known as arrhythmia, which is the main cause behind palpitation. Why some patients experience heart palpitations at night, during rest, when heart labor is smaller?
Heart palpitations at night can be determined by one of the following cause:

• too much stress and anxiety gathered during the daytime. It is a habit now that every time we go to sleep, we think again at the daily problems and try to find a solution, as it is said night is a good adviser. If your mind is concerned about certain problems happening in your life, you may be lying down and think about it over and over again, but the emotions and the psychical tension can generate palpitation.
• excessive consumption of caffeine before sleeping can generate insomnia and palpitation, if you drink a lot of coffee, especially before sleeping, you may consider giving up.
• smoking
• alcohol consumption
• medication-some drugs used to treat different diseases (like asthma, heart diseases, high blood pressure, cold) can determine palpitation: pseudoephedrine used in cold medication, theophylline for asthma etc.
• pregnancy
• fever-it is well known that body temperature elevation is associated with rapid heart beats and sometimes with palpitations
• vigorous exercise before sleeping
• breathing problems determined by lung diseases determine a low level of oxygen in the body, which can lead to heart palpitations at night
• heart problem-patients with heart failure may develop paroxysmal nocturnal dyspnea (shortness of breath that occurs suddenly during night in patient with left heart failure) and palpitations, forcing them to wake up and search for an open window to get fresh air
• hyperthyroidism (a higher level of thyroid hormones can determine irregular or rapid heart beats)
• elevated blood pressure

If I have heart palpitations at night-how can my doctor discover if there is something wrong in my body?
Yes it is possible. For patients that have these symptoms only during night it is difficult to  diagnose them during a simple medical visit, but if a special device called holter ecg is used, then this is no longer a problem. Holter ECG is a portable medical device that the patient “wears” for 24 hours and it records heart activity during this period of time.
Heart palpitations at night-treatment
Heart palpitations at night can be treated only after proper tests are made in order to establish the correct diagnosis. In many cases, palpitations have no serious cause and a short time treatment associated with a life style change can be the “cure”.
Special precaution in patients with heart palpitations at night:

• avoid consumption of alcohol, coffee, drugs (marijuana, cocaine) or smoking
• avoid stress and anxiety-there are many types of techniques used against anxiety (psychotherapy, sports, taking vacation, travelling etc.)
• sometimes medication is needed in order to control anxiety
• respect your hours of sleep
• avoid if possible the intake of medication that stimulate palpitations

Heart palpitations at night can be very uncomfortable, but sometimes a simple change in the  daily habits can make them disappear.
