Adenosine may be safely used during pregnancy. [18] Adenosine can be administered together with nondihydropyridine calcium channel blockers. [16] Calcium channel blockers such as verapamil and diltiazem have a longer half-life compared to adenosine.
If the fast heart rate is poorly tolerated (e.g. the development of heart failure symptoms, low blood pressure or coma) then AVNRT can be terminated electrically using a cardioversion. In this procedure, after administering a strong sedative or general anaesthetic , an electric shock is applied to the heart to restore a normal rhythm.
Both doctors say that signs and symptoms of valve damage can vary, but the main ones to be aware of are shortness of breath (particularly during exercise or any form of exertion) and chest pain or ...
Symptoms usually include one or more of the following: orthopnea (difficulty breathing while lying flat), dyspnea (shortness of breath) on exertion, pitting edema (swelling), cough, frequent night-time urination, excessive weight gain during the last month of pregnancy (1-2+ kg/week; two to four or more pounds per week), palpitations (sensation of racing heart-rate, skipping beats, long pauses ...
Peripartum cardiomyopathy is a heart failure caused by a decrease in left ventricular ejection fraction (LVEF) to <45% which occurs towards the end of pregnancy or a few months postpartum. Symptoms include shortness of breath in various positions and/or with exertion, fatigue, pedal edema, and chest tightness.
If these maneuvers fail, using intravenous adenosine [4] causes complete electrical blockade at the AV node and interrupts the reentrant electrical circuit. Long-term management includes beta blocker therapy and radiofrequency ablation of the accessory pathway.
A normal resting heart rate is 60 to 100 beats per minute. A resting heart rate of more than 100 beats per minute is defined as a tachycardia. During an episode of SVT, the heart beats about 150 to 220 times per minute. [9] Specific treatment depends on the type of SVT [5] and can include medications, medical procedures, or surgery. [5]
Signs and symptoms of pregnancy are common, benign conditions that result from the changes to the body that occur during pregnancy. Signs and symptoms of pregnancy typically change as pregnancy progresses, although several symptoms may be present throughout. Depending on severity, common symptoms in pregnancy can develop into complications. [1 ...
