Pulsatile tinnitus is caused by blood circulating in or near your ears.
与大多数类型的tinnitus，脉冲耳鸣具有您的耳朵拾起的物理声音来源。这是通过动脉循环的血液的放大声音。
您听到其他类型的耳鸣的响声或嗡嗡声是神经在异常的电信号从耳朵移到大脑的异常电信号的结果。
脉搏性耳鸣的主要症状是听到耳朵中的声音似乎与您的心跳或脉搏相匹配。当您听到耳朵中的声音时，您甚至可以掌握自己的脉搏。
您可能还会注意到心pal或头晕。您应该尽快对医生评估这些症状。如果您遇到突然的胸痛或其他心脏病发作的迹象, call 911.
脉动耳鸣有许多可能的原因，但它们都源于循环问题。最常见的原因是：
When your blood pressure rises, the force of blood against the inner walls of your arteries increases. More forceful blood flow in arteries in or around the ears is easier for your ears to detect.
由胆固醇，脂肪和废料堆积引起的动脉阻塞会导致血液流动。如果这是原因，您可能会听到其中一只耳朵的节奏声。
动荡的血流
Narrowed neck arteries (颈动脉) or veins (jugular veins) may also cause a change in blood flow to and from the head. Your ears may pick up on this turbulent or irregular circulation, causing pulsatile tinnitus.
Head or neck tumors
A tumor that presses against a vein can also cause pulsatile tinnitus.
异常capillaries
A problem with the tiny blood vessels that help connect your arteries to your veins, or capillaries, can cause pulsatile tinnitus.
Make an appointment with your doctor if you think you’re experiencing pulsatile tinnitus. Your exam will start with a review of your symptoms and your medical history.
医生可能会使用听诊器听取您的胸部，脖子和头骨。如果您的医生还可以听到脉动的噪音，那么您就有客观的耳鸣。如果没有，它被标记为主观脉冲耳鸣。
您还将进行听力测试，以确定一只或两只耳朵的听力损失。您的医生也可能会订购一些成像测试。这些包括：
You may also be tested for high blood pressure and given a blood test to check for thyroid disease or贫血.
If it appears as though you have pulsatile tinnitus, you may be referred to a cardiologist (heart specialist) for an exam and screenings for possible circulation problems or high blood pressure.
Pulsatile tinnitus can cause sleeping problems. Poor sleep can lead to:
- difficulty with concentration
- low energy
- 心血管问题
- weight gain and other metabolism issues
脉冲耳鸣通常通过解决根本原因来治疗。
高血压，静脉和动脉疾病通常可以通过药物和生活方式的变化来治疗，包括：
- a low-sodium diet
- 定期运动
- no smoking
- 减轻压力
如果原因与动脉或静脉中的特定问题有关，则可能需要手术或导管程序来治疗这种情况。有时将称为支架的柔性网状管放在阻塞的动脉中以打开并改善血液流动。
Sound therapy
If the blood vessel can’t be treated, you may benefit from sound therapy. This involves playing background noise, such as soft music or “white noise,” to distract you from the tinnitus or change your brain’s sensitivity to the pitch of the tinnitus. You may also benefit from cognitive behavior therapy, a form of talk therapy designed to change the way you think about a problem in order to change your emotional reaction to it and the way you behave toward it.
脉冲耳鸣的前景取决于根本原因。引起脉动耳鸣的大多数疾病都可以通过药物和生活方式改变来治疗。
