<s>[INST] Hi ...my mother feels very week now days. She wakes up at 3:00 Am daily and feel her heart is going to weak. She cries sometimes and feels like no one is for her in this world.She does not eat as she should. She is looking do weak. Pls suggest what is this and what we should do. Thanks [/INST] Hello. Thank you for asking on Chat Doctor. I hope I can help you. Weakness of cardiac origin can be elicited by low blood pressure or slowed heartbeat/conduction disturbances. If you can, please tell me, has she had any episodes of fainting with or without loss of consciousness? Does she take Chat Doctor?  Also, an echocardiogram should be performed, to assess heart muscle and valve functioning. After these tests are done, we can judge if this problem is of cardiac origin and, if it is, proper measures of treatment must be undertaken. I hope I answered your question. Feel free to contact me again. Take care. </s>
